A/N: First, a quick thank you to the people who reviewed:

kk241289: "Who is she?" will be answered eventually! And I'm glad you think it's getting suspenseful. Just wait, it gets even better!

tvspaz626: Keep wondering. Hehe.

In general, I know it's kinda slow and a little boring in the beginning. But take my word for it, it gets really good! In coming chapters, you find out a lot of . . . interesting facts. I don't want to say what because I don't want to give anything away. But in coming chapters there is something you wouldn't expect at all, a little – cough – trip, and a very awesome big battle with a surprising ending. There are 12 chapters, all typed and ready to be posted. So, bear with me. It gets much better! Please, review!! And please, ENJOY!!

"Hey, hey, get away from there!" Piper growled, rushing forward and snatching the Book off its wooden stand.

The girl blinked, frowning at Piper. "What? It's just a book. I was looking at it. What's the deal?"

"What were you doing snooping around our house anyway?" Prue demanded, stepping forward, arms crossed.

The girl suddenly looked defensive. "I wasn't snooping. I washed up and then I wanted to walk around and see the rest of the house. It's really big and pretty."

"Yeah but-"Piper said, but paused. She had just realized something. "The bathroom door is locked from the inside. How did you get out and up here?"

"It wasn't locked when I left. Maybe when I opened the door, I hit the lock by accident so when I closed it, it locked," she replied.

This, however, wasn't much of an answer, or a convincing one at that. Prue, Piper, and Phoebe glanced at each other, then at the girl.

"What's your name?" Prue asked, but the girl ignored her and stared out the window instead. "I asked you a question. What's your name?" Still, the girl ignored her.

Phoebe stepped closer to the girl. "Hey, if you're in trouble or something, we can help you." She moved forward, hand out to place on the girls shoulder.

The girl jerked forward and spun around before Phoebe could touch her. She dodged around her and sat down on the antique couch. "Did you guys say something?" she asked, looking at each sister in turn.

"Okay, this cat and mouse game stops now," Prue snapped. "You heard Piper ask for your name in the kitchen and you heard me just now. So stop ignoring us and answer me."

The girl stared at a dusty picture on one of the old dressers. She tilted her head, then turned to look at Prue.

"What is your name?" Prue said slowly and emphasizing each word.

"Sky," the girl answered, all too quickly.

"Wow. Considering you pretended to ignore us before, that was some quick answering just now," Phoebe commented, stepping beside Prue and Piper.

Sky shrugged. "Does it matter?"

"Where's that tow truck?" Piper asked, crossing her arms. "It's been half an hour. They should have come by now. It's a fifteen-minute walk to the gas station.

"Maybe they got lost," Sky answered.

Piper frowned. "Wait. You said they were going to get your car, then come here to get you. But you never told them our address. You don't even know our address."

"Oops," Sky replied, shrugging. "I'll walk there, then."

"But you said you were lost. You had no idea where you were," Piper argued.

"I'll find it," Sky argued back.

"Tell us the truth, Sky. What's going on?" Piper demanded.

Sky's eyes narrowed. "I told you the truth. My car broke down. The tow truck probably picked it up already and it's at the gas station. I'll just walk over there and get it."

"So go. Go get your car and get out of here," Piper snapped.

"Do you treat all the guests in your home like this?" Sky growled.

"Guests don't snoop around and refuse to give us their name," Piper shot back.

"I told you my name, didn't I?" Sky argued.

"Okay, enough!" Prue shouted. "Stop bickering. You two sound like little old ladies. Plus, you're both so stubborn that it could go on for hours. So enough already."

Sky and Piper stopped arguing, but they glared daggers at each other.

"Okay," Prue sighed. "Piper, Phoebe." She nodded her head in the direction of the door and her sisters followed her outside the attic and down the steps to the second floor, Piper still clutching the Book of Shadows.

"I have a weird feeling about her," Piper said shortly, still pissed off about the way Sky was acting.

"Don't we all," Prue replied. "I think she's lying about how she got here. I think she's lying about her name. And I think she's hiding something. Did either of you notice the way she keeps avoiding Phoebe's touch?"

Phoebe nodded. "Yeah, so?"

"If she was hiding something, or if she's our innocent, what would happen if you touched her or something that either she's touched or that belongs to her?" Prue asked.

"Well-" Phoebe frowned. "Oh." Then, her eyes widened in understanding. "I'd get a premonition! And every time I've tried to touch her, she's moved away. And in the kitchen, I went to pick up her glass and she snatched it away."

"Uh-huh," Prue said, nodding.

Piper bit her lip, remembering the weird feeling she had had earlier. But it didn't fit, so she didn't voice it yet. She glanced at her sisters. "What if she just doesn't like being touched? Or maybe she just happened to move before Phoebe could touch her. And it is hot. She said she'd been walking for an hour, so she probably just wanted to take her water with her. I mean, come on. Why does everything have to have a magical explanation?"

"Because it's who we are. Magic just seems to find us," Phoebe replied with a shrug.

Piper was about to reply when the attic door snapped shut and she spotted Sky standing on the steps. "How long have you been listening?" she demanded.

"I wasn't listening. I just came out of the attic like, two seconds before you saw me,' Sky replied defensively.

Piper narrowed her eyes. "No, you were standing there and listening. I never heard the attic door open, so you must have been standing there for a while."

"You didn't hear it open because you were too busy chitchatting," Sky snapped.

"I would have heard it. It makes a creaking sound," Piper growled.

"I'm so sick of you accusing me of every little thing I do!" Sky yelled, crossing her arms.

"Well you have to admit that so far, all you've done is cause us to become suspicious," Piper replied bitterly.

"Suspicious? You make me sound like I'm a criminal or something! All I'm guilty of is driving a crappy car that broke down on me and getting stuck here in crappy San Francisco and I ended up here because no one else would let me use their phone," Sky snapped.

"And why is it that you ended up here? Can't be a coincidence," Piper argued.

"A coincidence? What the hell are you talking about?" Sky shouted, a confused look on her face.

"Give me one reason why we should believe your story," Piper demanded.

Sky crossed her arms. "I would if there wasn't a bald dude with tattoos standing behind you with a knife."
