“An increasingly tense race to find who’s doing the killing—and who’s going to survive.” —The Oregonian  First they were five. Then they were four.  Whose turn will it be next?  At Bristol High they were an elite clique known as the Five Firsts: Amanda, Bailey, Carmen, Delta and Zora . . . ABCD & Z. They could have accepted their classmate, Emmy, as E, but with her bookish disposition and her embarrassing status of scholarship student to boot, they rejected her and chose wealthy Zora instead.  At a pre-graduation party just before the end of senior year, Lance Ventura, the hottest guy in school, falls down an embankment toward the river and is barely rescued in time to save his life. One of the Five Firsts, Carman, rushes to save him, but isn't so lucky. Her sudden death causes a community to mourn and rumors of foul play to swirl, but the tragedy is ruled an accident.  Fast forward ten years and the classmates all meet again at the high school reunion. Some of them have had good fortune in their lives. Others, not so much.
