The other side of the Dark By:Joan Lowery Nixon

I think everyone should read this book because it very entertaining and very mysterious? The main character is Stacy, 17, awakens from the coma she's been in for four years, following a gunshot wound, and finds her world is drastically altered. The shooting incident that injured her also killed her mother. Her older sister is married and pregnant. Hairstyles, clothing and friends have changed. Stacy, if her memory returns, can put the man who shot her and murdered her mother behind bars. Soon every face she sees looks both familiar and strange, and the attention of a boy named Jeff is welcomed and feared. Because of press reports, the murderer knows that Stacy can find him. She's afraid she's being watched. And when her memory and the truth about the killer come back to her, Stacy faces the darker side of herself.
