Hello reader and welcome to my fanfic. Before you read, there are a few things you might want to know about this fanfic.

This is slightly AU, but only because the Golden Trio, along with everyone else in Harry's year his in the sixth year, but this holds no events from the sixth year, and holds the events from the third year.

So basically, they're sixteen during the events of Prisoner of Azkaban

Also, yes this is an OC fic and some of you will feel the need to bash Callista Finch because you think she's a Mary Sue

Well that's nice, but please, keep your bashing attitude away.

Some of you might hate my plot

Then please just leave because honestly, if you hate it there's no reason to flame me. Why not spend your time with something you enjoy? That's what most people would rather do.

Also, this fanfic has a website! .com/

CHAPTER ONE: Professor Remus Lupin

"We'll see you next summer," Robert Finch said with a sad smile giving his daughter, Callista Finch a quick tight hug as the stood on the train platform.

"Don't forget to write Calli," Anita Finch, his wife insisted, wiping a tear from her eyes as she gave her only daughter yet another hug.

"I know mum," Callista rolled her eyes at how emotional her mother was being, it seemed to her that after five previous years of the same exact goodbye she would get used to it. But apparently she didn't. Callista fought off a smile and released her mum from a hug. She turned to her dad, to give him another hug when she saw him turned away, ice blue eyes that matched her own staring out to the left. She turned as well, looking as well to see what her father was looking at.

"Is that Lucius Malfoy?" Robert asked, squinting at a figure in black walking down the platform, a shorter version of himself right beside him.

"And Draco," Callista answered, wrinkling her nose and looking around to see if it was possible to get on the train before he spotted her. After deciding that was impossible she simply braced herself for the inevitable insults and sexual innuendos that would come from Draco Malfoy as soon as he saw her. "Mum, why don't you go make sure all my luggage got on the train?" She said remembering the Malfoys's tendency to insult any and all muggles.

Just as her mother had walked away Lucius and Draco Malfoy made their way to the Finches.

"Robert Finch, how have you been doing?" Lucius asked in his trademark tone that made everything he said sound like an insult.

"Lucius, I've been fine thank you." Robert answered, careful to keep his voice formal and not allow his dislike for the Malfoys to show.

"It's great to see you Callista," Draco said, running his eyes up and down her figure in a way that made Callista instinctively cross her arms across her chest. "How was your summer?"

"Fine," She answered as politely as she could, noticing that Lucius had taken to conversing with her father, leaving her with Draco.

"You look good, Finch. You've uh…grown…" He smirked, staring at her long legs and bringing them back up to her chest and she crossed her arms tighter. Despite the fact that she was tall, she didn't top Draco's six feet and that made her even more uncomfortable, knowing that he could easily dominate her.

"Yeah…" She muttered, keeping her eyes hard and not looking away to let him win.

"Draco you should get on the train now, you don't want to be late," Lucius' voice remained the same tone it always was, showing no affection for his son.

"I'll see you later," Draco turned toward Callista, a trademark smirk on his face, eyebrows raised suggestively, before he stepped on the train and out of sight.

"Goodbye Robert," Lucius said before turning and walking away through the crowd, not bothering to look out for the people in his way.

"Well I should get going so I find a seat on the train," Callista turned to her father, giving him one more quick hug, she waved and smiled at her mom who was standing off to the side, her handkerchief in her hand as she continued crying. "Bye."

As soon as Callista was on the train and away from her parents she took a moment to relax and be happy about the fact that she was finally a 6th year, only two more years left at Hogwarts. As much as she loved her family, she also loved Hogwarts, loved her friends and was excited to be spending even the Holidays at school, since her parents would be out, visiting her aunt's cottage in Paris.

"Callista!" A familiar voice called from behind her, just as the train was leaving the station.

"Hermione!" Callista recognized her best friend coming toward her and gave her a quick hug. "It's so great to see you! Hi Harry, Hi Ron," She added, noticing the two boys coming up behind Hermione. Harry said hello while Ron was too busy waving to his parents on the train platform as it faded away.

"We should go find somewhere to seat," Harry pointed out, noticing that most of the students had already found a spot in a compartment and most of them would already be full. They continued on searching until finally they reached the back of the train.

"Everywhere else is full," Hermione pointed out when they reached a compartment that had only a huddled mass in the corner, that upon a closer look seemed to be a new professor sleeping.

"Is he really asleep?" Harry asked once he, Ron, Hermione and Callista had entered the compartment.

"Looks like." Ron muttered, taking the seat directly across from Professor Lupin—as his suitcase said he was—, followed by Harry and then Hermione, none of which wanted to sit next to the Professor. Rolling her eyes, Callista plopped down on the only open seat, next to Lupin.

"Alright, well I need to talk to you three in private." Harry muttered, sliding the compartment door shut. Callista meant to listen, truly she did, and she even listened to most of it. But this story seemed to be nothing, considering their past six years at Hogwarts.

Even now, on the train ride to the school, listening as Harry told them of Sirius Black's plot to capture and kill him, she couldn't register the proper amount of horror. Perhaps it was six years of every other Voldemort supporter that came across Harry, trying to kill him, perhaps it was the excitement of almost being done with school, but Callista simply wasn't as horrified as Ron or Hermione were. Zoning back into reality, she crossed her legs, skirt riding up a little but she smoothed it down, brushing her hair behind her ear. Shifting slightly in her seat, Callista's arm brushed up against Professor Lupin. She stared at the professor out of the corner of her eyes, noticing how thin he was. He was tall too, she could tell by the uncomfortable way he was folded up in his seat. His hair was a shade of light brunette and was incredibly messy. His skin was pale and if she didn't know any better, she'd say he was deathly ill. But he was a professor; Dumbledore wouldn't hire him if he wasn't in good health. Callista shifted once more and in that instant, she felt the train pulling to a stop.

"We can't be there yet…" Hermione muttered, looking around, as the door to her compartment was shoved open. It was Ginny Weasley whose blue eyes were wide and terrified.

"Ron!" She exclaimed. "Why've we stopped? Why has the train stopped?" She panicked, and almost as if on cue, the lights blacked out and Ginny let out a terrified squeaked, falling backwards, half on the seat next to Callista, half off of it. Scooting closer to Lupin, she allowed Ginny to take a seat next to her, despite being crammed in next to Lupin. Their compartment fell silent for a moment before Ginny spoke up again. "What's happening?" She asked.

"Hush a minute…" Callista whispered, but her whispers weren't heard as Hermione winced and her cat let out a hiss.

"Ouch Ron! That's my foot!" She snapped and he whimpered a "sorry."

"Who's arm is that?" Harry muttered and Ron apologized once more, before the five of them heard a sharp hushing noise. They each turned, staring directly at Professor Lupin, who'd been asleep up until now. Callista felt her face color. He was gorgeous. His eyes were dark brown and so deep she swore she could've drowned in them. His shoulders were broad and despite the fact that he was thin, he still appeared to have some muscle definition and would've looked easily to be the most attractive guy she'd seen if his robes weren't utterly destroyed and he didn't have deep, dark shadows under his eyes.

Attractive…Callista pinched her eyes shut and quickly banished that thought, ignoring the fact that her body was tightly packed in next to his. Sodding Ginny Weasly…

"Professor, do you think we've broken down?" She heard Hermione ask, but Lupin just hushed them once more. Callista tensed in her seat, curious as to why they were being hushed, however she soon discovered why when an alarming cold swept over her and every ounce of her body went rigid. This was wrong…this was bad…The door to the compartment peeled itself open and a black, hooded figure with long, decaying hands glided into the compartment. A dementor…This was bad…a depression clouded over her and suddenly she couldn't think of anything but third year. Her breath caught in her throat and her arms flew around her waist, as though she was trying to hold herself together. Still, right as she was about to give up, to just collapse and cry, she watched Lupin stand up and noticed the silver plasma spewing out of his wand. The dementor recoiled and slid away, but not before Harry hit the ground.

"My God!" Ginny gasped and Hermione clung tightly to Ron, brown eyes wide and terrified. The lights came back on right then and the train started moving again, as though nothing strange had happened.

"Settled down Miss Weasley…" Lupin replied calmly, moving down to Harry, slapping his cheek lightly. "There's nothing to worry about." Although Callista easily knew it was a lie, and that he was just trying to comfort the girl. "Harry? Harry are you alright?" He asked, slapping Harry once more, causing him to slowly move back into a conscious state.

"What…?" He groaned, green eyes fluttering open.

"Are you alright?" Ron asked, both he and Hermione hoisting Harry onto his seat.

"Um…yeah…" Harry muttered, shaking his head. "What was that thing? And who was screaming?" He asked, looking at the group and Ginny paled noticeably.

"Harry…no one was screaming…" Callista muttered wrinkling her brow in a worried fashion.

"And that was a dementor, one of the guards of Azkaban…" Lupin replied, reaching into the pocket of his tattered cloak, pulling out an unopened chocolate bar for Harry. "Now here Harry, you should eat this." Harry stared at the bar of chocolate for a minute and Lupin pushed it forward. "Really, Madam Pomfry will have my head if you don't. Eat up." He insisted and Harry reluctantly took the chocolate bar, while Lupin handed Ron, Hermione, Ginny and Callista each a bar of chocolate as well.

"How do you know my name?" He spoke up, face unsure.

"You didn't think Dumbledore would leave me uninformed about you Harry, did you? But if you'd all excuse me, I'd better be off to have a word with the conductor." Lupin replied, excusing himself and Callista's sky blue eyes followed him. Well…this was sure to be an interesting year, she though, pushing thoughts of him down.

***

The feast had begun at last. Dumbledore had made his announcements about the dementors, Profesor Lupin and his other topics. The sorting ceremony took place and several new Gryffindors made their way to the table and the food had appeared. Delicious, usually Callista couldn't keep her mind off of it. But not tonight. Tonight, her mind was filled with the train ride. Of being pressed up against this gorgeous teacher, this…dammit. She looked back down at her food, the meats the fruits and everything else on her plate and suddenly it was utterly unappetizing. This was not good. She tried desperately to remember her summer vacation, spending time at the beach, writing to her friends…but it was no use. Picking at a piece of chicken with her fork, she ran her free hand through her hair and allowed herself a moment to glance up at Professor Lupin, trying to look merely curious instead of actually interested. Much to her surprise, his eyes were on her too and her face washed crimson before she turned away, staring back down at her food with absolutely no appetite at all. This wasn't smart, she reminded herself. It wasn't a good idea when she went out with a seventh year while she was a third year and it wasn't smart now to even be looking at her teacher the way she was.

"Callista?" She looked up when she heard Hermione's voice and saw that she was looking at her in a very concerned nature. "Are you feeling ill?" She asked and Callista nodded weakly, figuring that lying was a better option than saying "no" and having Hermione start questioning her lack of eating.

"A little homesick I suppose, just because last summer was wonderful." She said quickly. "I'm sure it'll pass in a few days." She replied simply, turning back to her food, hoping that she could manage to just scarf some down but she knew she couldn't. She had a fairly low tolerance for over eating. So, for the rest of the feast, she tapped her toes on the floor and went over Hogwarts, A History in her head, hoping that

she could ignore the rest of the world…

***

Callista didn't sleep well all that night. It was hard enough sleeping with Hermione's constant sleep-talking and the fact that Luna Lovegood got up and sleepwalked each and every night, the floors creaking loudly as she did, but with the present situation at hand, she barely slept a wink. She'd spent the night talking herself out of any girly fantasies she could conjure up, fighting with herself over and over again. 'You're a sexual being you're allowed to be attracted to him' 'But where did attraction ever get you before? Broken hearted? Crying every single day? Suicidal?' 'No one gets out of the teen years unscratched sweetie, besides its not like you need to fall madly in love with him and try to have some kind of affair with him. Admiring from afar is perfectly natural.' 'But he's a teacher!' 'Well so was Lockheart, but the bulk of the schools female population was in love with him.' ' I'm not going to marry the man, so what's the point in looking anyway?'

That same argument, over and over again, all night until finally, at about four in the morning, she passed out from sheer exhaustion. And of course, being that breakfast ended at 8:30, she'd managed to sleep in until 8:45, with fifteen minutes until her first class of the day started and being that it was her first year in Divinations, she had no idea where the room was. Rushing to just pull her curls—which had gone frizzy when she'd slept on them and didn't have the time to shower first thing in the morning—back into a dark crimson ribbon, tug on her uniform, apply some concealer to the huge dark circles under her eyes and apply the rest of her make up before brushing her teeth and jetting out of the common room, books and bag in her arms, stomach empty and grumbling. She tripped several times, bumped straight into Draco Malfoy, knocking him down—which wasn't necessarily a bad thing— and got completely lost, having to ask one of the paintings the way to Professor Trelawney's classroom. When she finally got there, she was a good ten minutes late and sincerely hoped that Professor Trelawney wasn't a thing like Snape and take ten points from Gryffindor, just because she was late.

Callista climbed through the trapdoor, expecting the worst, but much to her surprise, the fragile lady who she assumed to be Professor Trelawney was smiling at her.

"Ahhh, yes, Miss. Finch, I saw that you'd be late, but don't worry, Miss. Granger's still available to partner with." She smiled and Callista nodded, taking her seat next to Hermione who was scowling down at a cup of tea leaves.

"This class is ridiculous." Hermione whispered and Callista felt a smile tugging at the edge of her lips as Trelawney got to the instructions on what they were supposed to do. She hushed her friend's angry grumbling as Professor Trelawney approached her, handing her over her own cup of tea leaves. She set it down and then her already wide eyes widened even more.

"Goodness dear it seems as though you're going through quite a dilemma!" She said, clutching on the table as Callista's face flushed dark red.

"Um…no I think…you've got the wrong person, no dilemma's here." She lied but Trelawney shook her head.

"It appears that you'll be under extreme emotional turmoil, unless you can learn to think with your emotions, rather than logic. And also…something will change you completely sometime around Halloween..." Trelawney said, walking away as though this was completely normal.

"What was that all about?" Hermione asked, brow quirked. Callista bit her lip and shook her head, laughing nervously.

"You're right, this class is ridiculous." She replied.

Dammit…
