The Unbecoming of Mara Dyer, by Michelle Hodkin
How is it that Mara escaped the totally destroyed building with a sore head and all her friends died? Who bashed in the head of that dog-beating hulk of a man near her school? What strange things are happening to the wildlife in their new home town? So many alligators dead all at once! Could these incidents be related? And why does she have to be attracted to the best looking guy at school who can only mean trouble!
A strange and haunting tale of life with amnesia and self discovery.
