Friend or Foe?

Kara is in her 5th year; it's time for OWLs, more adventures with friends and all the fun Hogwarts can offer. Kara's future looks bright. She's aiming to become an Auror, willingly going against her family's wishes. But one person is out to wreck it for her and bring her to the dark side... where she belongs.

Disclaimer: I do not own any characters in Harry Potter, with the exception of Kara and maybe some other random people.

The story starts off with a flashback and then continues, revealing the main plot, with some more flashbacks.

Chapter 1 - A new friend.

Flashback

Kara swiftly made her way down Diagon Alley. It was nice to get away from her family once in a while. She stopped to pick up a few quills and some ink, parchment and note books. She handed the shopkeeper the exact change and put her writing materials carefully into her bag.

She was so excited to be finally attending Hogwarts. She had been waiting almost five years for the day she would get her letter from Hogwarts. She looked back at her list and noticed that she had almost collected all her supplies. All she was missing was a textbook she had overlooked.

As she made her way to Flourish and Blotts she looked at the displays in every shop window. The bookstore was only a few steps away and she wasn't paying much attention to where she was going and she tripped over a loose cobblestone. She lost her balance and expecting to hit the cold stone road in seconds, she shut her eyes tight. But she never felt them, someone had broken her fall. She opened her eyes to look upon her saviour and they widened in shock. She quickly pushed herself out of her saviour's arms and eyed him warily.

"You're a Weasley!" she said.

"Yes I'm George Weasley as a matter of fact."

"Oh, well thank you for, um..." she started at a loss for words. She felt herself turn slightly pink in the cheeks.

"Breaking your fall?" George finished for her. "Your new around here aren't you? Well I mean I haven't seen you around here."

"No I guess you haven't, but I've been in Diagon Alley plenty o' times." She answered, flinging her long blond braid over her shoulder.

"Do you go to Hogwarts? 'Cause I'm sure I haven't seen you there, although you do seem familiar."

"No I'm starting this year, but my brother already attends Hogwarts." Kara said feeling the heat in her cheeks disappear.

"Hey George, who you talking to?" came a voice behind him.

"Oh hey Ron, this is..." George started to introduce them, then turned to Kara, "I don't think I asked you your name."

"Oh, I'm Kara." She said shyly giving them a faint smile, the heat in her cheeks rising anew. "And you must be Harry Potter," she said nodding in his direction. "And Hermione Granger and you are Ron Weasley. Right?"

Harry, Ron and Hermione nodded.

"How did you know?" Hermione asked curiously.

"My brother has told me all about Hogwarts and the people he's met."

"Oh, and who's your..." Harry started but was immediately cut off by Mrs. Weasley's beckoning voice.

"Come on children. We have to get your school books."

George turned back to face Kara, while the others filed into Flourish and Blotts.

"Would you like to join us? I mean if you've got nothing else to do."

"Sure, I'd like that."
