[An] astonishing pleasure.

–Seattle Times

A graceful, moving, and compelling novel. Jacquelyn Mitchard at her finest.

–Scott Turow, author of Innocent

A poignant and unforgettable novel from Jacquelyn Mitchard, author of the monumental New York Times bestsellers The Deep End of the Ocean and The Most Wanted, A Theory of Relativity is a powerful tale that explores the emotional dynamics and dramas of two families fighting for custody of a young child. The very first author selected by the Oprah Book Club, Mitchard is a matchless, wise, and warm chronicler of families and their human foibles–and A Theory of Relativity is contemporary women’s fiction at its best, a must-read for fans of Sue Miller, Jane Hamilton, and Elizabeth Berg.
