Accident - Danielle Steel

Although frequent business meetings keep her husband, Brad, away from home, Page Clarke feels blessed with her happy family and comfortable marriage. They have a house near San Francisco and she keeps busy looking after their seven-year-old son, Andy, and their teenage daughter, Allyson.
Allyson, at fifteen, is trying her wings and one weekend, instead of an evening with her friend Chloe, the girls lie and go out with two older high school boys. But a Saturday night that was supposed to be fun ends in tragedy when their car collides head-on with another.
