John Gregory Brown's debut novel examines family, race, and faith in a heartbreaking tale of identity, devotion, and regret. The story centers on the Eagen family of New Orleans, Irish Catholics of ""mixed blood"" in a city where race defines destiny. In 1965 Thomas Eagen and his twelve-years-old twins, Meredith and Lowell, abruptly drive off, leaving his second wife, Catherine, and their home. As they cross Lake Pontchartrain, a section of the bridge collapses, injuring Murphy Warrington, an African American man who once worked for Thomas's father. Murphy becomes the catalyst for a series of revelations about Thomas's light-skinned black mother and the reasons she abandoned her husband and son when Thomas was an infant.
