If I Stay (If I Stay #1) by Gayle Forman

In the blink of an eye everything changes. Seventeen ­year-old Mia has no memory of the accident; she can only recall what happened afterwards, watching her own damaged body being taken from the wreck. Little by little she struggles to put together the pieces- to figure out what she has lost, what she has left, and the very difficult choice she must make. Heartwrenchingly beautiful, this will change the way you look at life, love, and family. Now a major motion picture starring Chloe Grace Moretz, Mia's story will stay with you for a long, long time.
