Imposter by Jill Hathaway
Be afraid of your shadow...
Vee Bell has witnessed murder. She nearly died trying to track down the killer, all because of her secret condition. She'd tell her best friend Rollins but lately he seems more interested in his colleague Anna than her. Maybe she should confide in her long-lost aunt who's turned up out of the blue?
All of a sudden life is happening in reverse: Vee is waking up in weird places not knowing what she's done. The only thing she's sure of is that someone is messing with her. And when a prank goes horribly wrong, this time the hands with blood on them might be hers.
