I have recently had to edit this after a few canon errors which were set right by "book 'em again" Thank you so much for your help!

Hello! This is my first ever Hawaii Five-O fan fiction and I'm really excited for it. I'll excuse any errors because I've only seen seasons 1 and 2 of the show. If you do have any help for me I'd be glad to take it! Please don't flame!

Chapter one

Aloha

A knock sounded on Steve McGarrett's office door causing him to look up from the letter he was writing.

"Yes, what is it?" he called. His secretary, Jenny, opened the door and flashed him a smile.

"You wanted me to let you know when it's twelve thirty Boss." She said cheerfully. Steve nodded. "Thanks Jenny."

Jenny backed out the door and left Steve to himself. He checked his watch. It was indeed half past noon and his sister's plane was to come in at one. He plucked his jacket from the hanger on the hat rack and left the office, giving Jenny instructions to cancel all appointments for that afternoon.

"Steve!" Steve turned around and watched as his friend and fellow detective, Danny, ran up to catch up with him.

"Almost one." Danny said slowing to a walk beside Steve.

Steve grinned. "Yeah, I know. Just on my way to the car."

Danny followed Steve to the car. "Want me to come with you?"

Steve shrugged. "Do you want to?"

"Think your sister will mind much?" Danny asked.

"I don't think so. Lois would probably love to meet a strong, handsome guy like you," Steve teased. He and Danny made it to the car and Danny waited for Steve to unlock the car. The two of them climbed in and the car cruised it's way along to the airport.

"So, how old is your sister?" Danny asked. He peered out the window at the familiar Hawaiian landscape.

On the driver's side, Steve replied. "She's fifteen. Like I said, she's my kid sister. After Mom remarried this military man, Lois was the last kid she had before my stepdad died in Vietnam." There was a tinge of sadness to Steve's voice. Dan assumed it came from the fact that he had lost both father and stepfather.

"Oh." Danny had wondered if Lois was Steve's full sister or his mother had remarried.

Steve chanced a glance at Danny. "Mom's going to be tied up this summer and can't keep an eye on her. Mary Ann offered but I figured it was time she spent the summer with me."

Danny chuckled. "Wow, Steve, the whole summer? You can handle that?"

Steve smacked Danny's arm. "Hey, she's a good kid. Smart-would make a good detective."

Danny started in surprise and looked at the older detective. "No way! What makes you say that?"

"Well Danno, the last time I saw her was when she was ten. She said she found the neighbor's dog. The thing had been lost for a week and she tracked this thing down just from hearing me tell mom and dad stories about work." Steve remembered when he visited home and the little girl had tackled his knees in a hug and in the breathless manner that most little kids have, told him about how she found the dog.

"Yeah, last year I got a letter saying that she was testifying in court against some sexual harasser in the school. Apparently the cops couldn't find evidence that led to the guy and she went looking and scraped up enough evidence to convict the guy," Steve continued.

Danny looked impressed. "Wow, a real Nancy Drew then, huh?"

Steve chuckled. "Don't tell that to her. She gets embarrassed easily."

"I'll remember." Danny scrunched his eyebrows. "Say, wasn't that the case on the news? The one where one of the girls was found killed?"

Steve nodded. "Yeah, they couldn't nail him on a murder charge though."

"Too bad." Danny pursed his lips and watched as they pulled into the airport parking lot. He hated hearing about how criminals got off scotch free for a crime they clearly committed. He mentally shrugged. Sometimes he didn't know whose side the U.S. constitution was on, except that it was made for the people, by the people, and that included all the people… including criminals.

The two made their way to the airport lobby and Danny sat in one of the many chairs supplied for the public. Steve on the other hand stood and checked his watch a few times. Danny smiled inwardly, sometimes Steve could be one of the most patient persons he knew and then, well, he could be just as impatient too.

"So how will you recognize her?" Danny asked.

Steve squinted at the large clock hanging over the glass entrance doors.

"She said she'd be in a school uniform and that a red bandana would be in her hair," Steve said after a moment. Danny let out a breath that made Steve look at him.

"What?" he asked.

Danny waved his hand. "Quite the combo."

Steve grinned. "Gotta recognize her somehow." He looked back to the sudden flood of people entering the lobby. Passengers from the last plane, Steve thought. He gazed at the people coming out, searching for a red bandana. He thought he saw one, but then it disappeared back into the crowd. Then he saw it again, along with the lanky fifteen year old that was his sister.

He waved and shouted her name; making the girl and several other people glance in his direction.

"Lois! Over here," he shouted, waving at her. The girl waved back and a smile broke out on her face. She hefted a backpack on her shoulder and took off towards them.

She slammed into Steve like a truck in a wall, making Steve stumble back a step. Steve wrapped his arms around her and hugged her fiercely.

"Oh, Steve, I'm so glad I'm here!" Lois gushed. "I thought I'd never get off the plane."

Steve kissed the top of her head and held her out at arm's length.

"Well Lois, you've gotten tall since the last time I saw you." He said. Lois laughed.

"The last time you saw me, I was only ten!" she said. She hugged Steve again and re-shouldered her backpack. She looked around the airport then eagerly out the doors.

"So far," She said "Hawaii's better looking than what you sent me on the postcards."

Steve scratched his head. "Yup, sure is." He caught Danny's eye and waved him over. He put his arm around Lois's shoulders and held out a hand to Danny.

"Lois, I'd like you to meet a friend of mine and a fellow detective." He grinned at Danny. "This is Dan Williams; we call him Danny."

Danny shook Lois's stretched out hand. "Aloha." He said.

"Nice to meet you." Lois replied. She looked at Steve. "I'm going to use the ladies room to change." She pointed to her backpack. "School uniform's a bit drab."

"Okay."

Steve watched her go and smiled fondly. The girl had certainly grown up some, but her attitude hadn't changed a bit. He promised his mother that Lois would be kept safe and out of trouble the whole summer. His mother had a tendency to worry about family members.

"So that's Lois," Dan said, crossing his arms across his chest.

"That's Lois."

Danny chuckled and rolled his eyes at Steve. "She looks like you." He was surprised with the resemblance between the siblings, the two shared noses, the same firm jawline and crooked smile. He wouldn't have thought that them being half siblings there wouldn't be much of a likeness.

Steve brushed the comment off. "Of course, she's my sister. Besides, I think she looks more like Mom."

After a moment or two of waiting Lois returned sporting a red button down short sleeved shirt tucked into white shorts. The now matching bandana was rearranged to hold back her dark blond hair.

She grinned and spun around once. "What do we think?" She asked. "'Hawaii' enough for you?"

Steve wrapped an arm around her. "Groovy."

Lois picked her suitcase up and looked up at her brother. "So, where to first, big brother?"

Steve took the suit case from her and led the way out to the parking lot.

"I'm not sure; what do you feel like doing?" he asked. Lois shrugged. "Well," She said. "I'm hungry."

They reached the black '68 mercury that was McGarrett's car. Steve popped the trunk and placed the suitcase inside. Lois took the back seat and immediately rolled her window down. Danny stopped before he climbed in and looked inquisitively at Lois.

"Wanna sit up front?" he asked. Lois shook her head.

"No, you can. I like it fine back here." She replied. Steve came around front and started the car up. They cruised for a while before the radio transmitter buzzed with a call. Steve pursed his lips, an exasperated look on his face. He picked the radio up and hit the call button.

"This is McGarrett, what's up?"

Lois in the back perked up.

A voice replied over the radio.

"Steve, this is Chin. We've got a situation; potential jumper on 21st Street," the voice said.

"Have you talked to 'em?" Steve asked.

"Sure have, Steve," Chin replied over the radio. "The kid just won't come down."

Lois watched Steve's eyes widen. "Kid?"

"We guess she's about seventeen."

"Alright Chin; I'll be there in a minute." Steve hung the radio back up and gunned the car. They swerved and did a U turn back down the road. Lois shifted and buckled her seat belt.

"Steve?"

Steve grunted and maneuvered the car around a truck.

"Is that like…y 'know, suicide?" She asked. Danny turned around to save Steve the trouble of answering.

"Yeah. Only thing, they haven't committed suicide yet. We call them jumpers because they tend to like to, er, jump…from high places. You know?" he said. Lois nodded and glanced out the window again. She felt her pulse rise a bit as they came close to hitting a sedan. She looked at Steve to see that he had a relaxed but firm grip on the steering wheel. At least they wouldn't be crashing into anything, she reassured herself.

After a speedy drive to wherever 21st Street was, the mercury slid to a loud halt and Steve and Danny jumped out of the car. Lois followed after a moment's hesitation. She wasn't sure she should follow, but she felt uncomfortable waiting in the car.

There was a crowd of spectators held back by a few police officers. Patrol cars with flashing lights were parked around the several story high building. Lois even saw a fire truck parked.

She scooted around the patrol cars until she caught sight of her brother. Steve was with an older Asian plain clothes detective. The two of them were conversing and the Asian handed Steve a bullhorn.

Lois looked up at the top of a building to see a girl by the wall of the roof; she had both her legs swung over it, apparently ready to throw herself from it.

"This is Steve McGarrett of Five-O! What's your name?" Steve shouted, his voice magnified by the bull horn. "What do your friends call you?"

"Carrie! My name is Carrie!" the girl shouted back. From what Lois could see, the girl was extremely agitated. Scared even.

"Carrie, do want to get off the roof? We can help you if you do! We just want to help!" Steve returned.

Carrie shook her head vehemently. "No! Go away; I don't want your help. I just wanna die!"

"Why do you want to die? Is there any way I can help?" Steve asked.

"I just want to die. I can't live with him anymore!" she screamed.

"Who? Who can't you live with anymore? A boyfriend?"

The girl was silent and inched more towards the edge. Steve asked a few more questions and got no more answers. He turned back to Chin.

"Get some men up there." He said. Chin shook his head.

"We have some up there already. She threatened to jump when she saw them. She even slipped and almost fell. Steve, we can't move them in."

Steve rubbed his jaw and turned to Dan.

"Danno, I want you to drive Lois to the station and keep an eye on her, this may take a while." He said.

Danny nodded and ran off to the car and stopped short. Lois was nowhere near the car. He peered around wondering if the girl had gone to the edge of the crowd to see what was happening.

He hurried over and looked around, but to no avail. Lois was gone.

"Steve!" he called. Steve turned and raised his hands in a sort of "what" gesture. Dan shook his head. "I can't find her!"

Steve ran over. "What do you mean?"

"She's gone. I think she might have left to get closer to the scene." Dan said, his voice pitched with worry. It was not a place for a girl to get mixed up in.

Questions were answered though when a woman's voice called out in.

"There's another one!"

Steve and Dan swiveled to look where the commotion was and to both men's horror they could see the small figure of Lois on the roof of the building; her bright red shirt picking her out like flame.

"God, what's she doing?" Dan heard Steve whisper. He ran back over to chin and ordered him to get more men on the roof immediately.

All they could do now was watch.

Lois found herself wondering what compelled her to climb up the building. She was petrified of heights! All to save a life, she supposed. She had considered it stupid what she was doing, but the police were in a bad position and she could wait around to see the girl kill herself.

She looked to the very edge of the roof at the girl shivering on the wall. Lois slowly walked over; her shoes crunched on the gravel that covered the roof. Carrie must have heard her coming because the girl turned around and stared at Lois.

Lois gave a small wave. "Hi Carrie!" She said as cheerfully as she could muster. Carrie regarded her with mistrust.

"What do you want?" Carrie croaked. Lois shrugged.

"My name's Lois; can I sit with you? I just want to talk." Lois noticed when the girl turned that she had bruises on her cheekbones and arms. Lois sat on the edge next to the girl and willed herself not to look down.

She swung her legs over and peered at Carrie. "Why haven't you jumped yet?" she asked. Carrie laughed and wiped her eyes. "I-I'm afraid of heights. Can you believe it?"

Lois forced a laugh. "Really? So am I!"

Carrie looked at her. "Why are you up here then?"

"I wanted to get to know you, y'know?" Lois put a hand on Carrie's arm. "Look, if this is about a guy, I understand. You just don't have to kill yourself over him."

Carrie sniffed and choked down a sob. "I thought he was a nice guy. We met like, two weeks ago a-and, y'know he was like all cool and all. He took me out and stuff. I guess he just got a little weird, like he held up this other couple and y'know just started yelling at them. I wanted to break it after that."

Lois nodded. She let the girl talk. Obviously she needed to get it off her chest.

"He started hitting me and then said if I told my parents he'd do worse. Not like kill me. I told my parents and they called the cops. He got off it though. Then he like beat me up and—and well, I didn't want to but he said he'd hurt me more so I just y'know, let him." Carrie sobbed in earnest now. "I never wanted to; I swear to God! I just didn't want to do it! And if my parents found out about the baby, they'll take it to court and I don't know what to do! He'll probably find me and kill us both."

Lois hugged the girl. "Hey, well you don't have to do this. The police can help you." Carrie shook her head.

"No they can't; it'll only be worse!" she cried. Lois held Carrie's head up and made the older girl look her in the eyes.

"Look, if you jump, that baby dies too." Lois said. "And you don't want that because if you do, your boyfriend'll succeed anyway. My brother is down there. He's head of Five-O. I promise he can help you, if you help him by coming on down."

Carrie looked like she had been hit by a truck. The girl looked down at the pavement and then back to Lois. Then she scrambled off the edge like the devil was at her heels.

"My God!" she whispered and clutched her stomach. Lois followed and led the girl over to where the police officers were situated by the side stairs. They climbed down the stairs with Carrie safely with them.

Lois followed and practically slid down the stairs and onto the ground. The moment she made it to the front of the building she felt arms around her hugging her.

"Lois, thank God!" Steve said into her hair. Then he pulled her away from him, a dangerous spark in his blue eyes. Lois knew she wouldn't be getting off this one.

"Don't you ever pull a stunt like that again, or so help me I will pack you off on the next flight to the mainland. That was dangerous and you could have been killed, Lois."

"She wasn't going to jump." Lois said quietly. She felt her hands shaking as the adrenaline wore off.

Steve shook his head. "I don't care. Let police handle it, that's what we're here for."

Steve hugged his sister closer noting with concern that she was shaking. He hadn't remembered till she was on the roof that she had been scared of heights. A trait she had since she was five when she fell out a tree and broke an arm.

Steve quickly took off his jacket and wrapped it around Lois. She pulled it closer to her and wiped her nose.

"Thanks; don't know why I got so cold." She said. She watched as a couple peeled away from the crowd and hugged Carrie. All were sobbing.

"I'm glad she came down." Lois mused quietly. Steve led Lois back to the car and told her to wait a moment while he cleared up the situation. Meanwhile Danny came over and handed Lois a cup of water.

"That was some pretty good thing you did there," he said. "Not to mention stupid."

Lois shrugged, suddenly embarrassed that the relatively and much older detective had praised her. She mumbled something into the cup and turned pink up to her ears. Danny grinned and patted her shoulder.

"Steve said you get embarrassed with praise. Sorry, 'bout that," he said. Lois shrugged and sipped her water. At that moment Steve came back and nodded at Danny.

"Ready to go, Danny?" he asked. Steve got in the driver side and called back to Lois. "We're going to hit the station; I have something to grab before we head to my place. Is that fine with you?"

Lois nodded and rested her head against the seat. She felt extremely drained from her flight and the excitement of the day. Not to mention the seat felt so good…

After a few minutes of silent driving Steve pulled into a pizza place's parking lot and looked back at Lois, only to find her sound asleep. He smiled and told Danny to wait for him. He came back a few moments later with some pizza, which he placed in the back seat. Then they took off to the station.

Lois awoke to her shoulder being shaken gently. She hadn't even realized she fell asleep. Her eyes felt so sore she just had to close them and then…well, that was when she must have fell asleep.

"I'm awake. Darn jet lag," she mumbled, rubbing her eyes. Her nose twitched at the familiar smell of Pizza. Her mouth watered immediately.

"Oh my gosh, is that…?" She asked sniffing the wonderful odor.

"That is," Steve replied, helping her out of the car. Lois stretched and noticed she still had her brother's suit jacket on.

"Boy, I was out." She exclaimed.

Danny laughed. "Like a rock!" he said. "Steve was making faces at you."

Lois looked at Steve suspiciously.

"Please." Steve snorted.

Lois said nothing. Figured she would be asleep and completely vulnerable to the teasing of her brother.

She looked up at the beautiful Hawaiian sunset and felt the cool breeze tousle her hair. So far, she loved Hawaii already.

She followed Steve into the Five-O building and into his office where they were greeted by Steve's friendly secretary, Jenny.

The two plain clothes officers she saw at the jumper scene were there and Steve introduced her to them.

The older one was Chin Ho Kelly, and the big Hawaiian who was on the roof was Kono Kalakaua. Each was quite pleasant to her and got her laughing over the stories they told.

Chin of course reprimanded Lois for her actions but Kono on the other hand praised the girl for her bravery.

"That was some good thing you did there. Nice reasoning, kid with kid y'know." The hefty Hawaiian said. Lois chanced a glance at Steve who was frowning at Kono. She could tell her was going to light into Kono later.

They all had dinner at the station as a sort of "Welcome" delayed celebration. At any rate, Lois found it one of the best times she ever had. She felt like she could have known Steve's friends for years.

It was later that night when Steve finally locked up and took Lois to his apartment. He showed her the guest room and, of course, the bathroom.

She peered around her room curiously. "This is nice Steve."

Steve walked over and opened her window. "The breeze is good tonight. It'll help you sleep."

Lois looked up at her older half-brother. "Steve I'm sorry about today." She looked down and Steve could see a sort of pain cross her face then was gone in an instant.

"I had to do something, she was pregnant and her boyfriend beat her up. I know what that can do to someone." She finished. Steve wrapped an arm around her.

"Look, just promise me you'll let me know you have an idea next time." He said in a softer note. He hugged Lois and bade her a good night then left her alone.

Lois undressed slowly, donned her PJs, and crawled under the cool sheets. She had left the window open and a cool breeze flooded in making sleep come all the quicker.

so, exciting chapter I think. Just had the jumper to help work on Lois's character. Not to mention she comes back later in the story. Mwahahaha!
