Rabbit Hole, by David Lindsay Abaire
Becca and Howie Corbett had everything a family could want until a life-shattering accident turned their world upside down. The couple is drifting perilously apart. Caught up with them in their spiraling situation are other family members and an outsider, a high school boy whose life is equally traumatized by the accident. They all search for a path that will lead them back into the light of day. Winner of the 2007 Pulitzer Prize.
