"Don't Look Back" by Jennifer L. Armentrout

A girl stumbles out of the woods, scratched and bleeding and when the cops pick her up she can't even remember her own name. This is just the start of  Don't Look Back, by Jennifer L. Armentrout , a  suspenseful, creepy and sometimes pretty funny new book that takes amnesia, mean girls and hot guys to a whole new level.
Samantha, because that turns out to be the girl's name, is the daughter of very wealthy and somewhat dysfunctional parents and she even has a twin brother who, apparently, she wasn't all that nice to once she became best friends with Cassie, another rich, mean girl. They were the Queen Bees of their social set and school and bullied and made fun of pretty much every one else. Only now Cassie is missing. And maybe Samantha was the last one to see her and if her mind would only go back to normal maybe she could solve the mystery of Cassie's disappearance.
So, not remembering much of anything, Samantha tries to figure out what happened and why doesn't she feel as attracted to her OWN boyfriend, who she doesn't remember, as she is to her brother's best friend and the son of her parent's caretaker, Carson?
The Recommender does not give too much away, as you know by now, because I don't like anyone to spoil the fun of uncovering a mystery, so I'll just say that there are a lot of surprising twists and turns throughout this addictive story. If you're a fan of intriguing (and romantic!) mysteries then don't miss this one!
