Bullying, it is true and it happens all the time. Stella, a normal girl not really popular, she is smart and kind of pretty, has been through it to many times. She wakes up in the hospital one day and doesnt remember much, she had a major concussion and has other things going on. Nobody is telling her what event landed her in the hospital until a picture flashes in her mind while she is looking in the mirror, a picture of a girl covered in blood. And one last thing Stella is dying.

Challenge doesnt know her past. It is a normal school day, when she and two of her friends get called to go home. No problem right? Wrong, she finds that her boyfriends father is after her, and neither of them know why. She loses all of her memory until she looks in the mirror and finds a memory hidden in her mind.
