It's June 15th, the night of Nantucket High School graduation. Four juniors are driving home from a party when something goes horribly wrong and there is a crash. The driver of the car, Penny Alistair, is killed, and her twin brother, Hobby Alistair, is left in a coma. Penny's boyfriend, Jake Randolph, and Penny's friend Demeter Castle are unhurt--but suffer tremendous emotional damage. Jake and his family move to the other side of the globe--to the west coast of Australia--in order to escape the horrors of the accident. Demeter falls prey to alcohol abuse and other self-destructive behaviors that nearly lead to her destroying her own life.
