The accident was just that - an accident. It was dark, it was raining, Alison had two drinks in her, and the other car ran the stop sign. She just didn't get out of the way fast enough. But now a little boy - not her own - is dead, and Alison finds herself trapped under the twin burdens of grief and guilt, and feeling increasingly estranged from her husband...Charlie, who has his own burdens.

And the only thing he can focus on these days is his secret, sudden affair with...Claire, Alison's best friend. Bold where Alison is reserved; vibrant where Alison is demure, Claire has just had her first novel published, a thinly-veiled retelling of her childhood in South Carolina (which is also Alison's, in a sense).
