Divorce lawyer Leigh Huyett knows all too well that most second marriages are doomed to fail. Yet five years in, she and Pete Conley couldn't be happier with their blended family.

But one rainy Friday night, on the way back from celebrating their anniversary, Peter and Leigh receive horrific news. Peter's son Kip, a high school senior, has crashed his truck and been arrested for drunk driving. And Leigh's fourteen-year-old daughter, Chrissy, was with him.

Twelve hours later, Chrissy is dead and Kip is charged with manslaughter.

Reeling with grief, Leigh nonetheless does her best to rally behind Peter and Kip. That is, until Kip changes his story and claims that he wasn't driving after all--Chrissy was, and he swears there is a witness.

As they hurtle toward Kip's trial date, husband and wife are torn between loyalty to their children and to each other, while the mystery of what really happened that night looms large.
