James Patterson has written a love story—a powerfully moving and suspenseful novel about families, loss, new love, and hope.

Katie Wilkinson has found her perfect man at last. He's a writer, a house painter, an original thinker—everything she's imagined she wanted in a partner. But one day, without explanation, he disappears from her life, leaving behind only a diary for her to read.

This diary is a love letter written by a new mother named Suzanne for her baby son, Nicholas. In it she pours out her heart about how she and the boy's father met, about her hopes for marriage and family, and about the unparalleled joy that having a baby has brought into her life. As Katie reads this touching document, it becomes clear that the lover who has just left her is the husband and father in this young family. She reads on, filled with terror and hope, as she struggles to understand what has happened-and whether her new love has a prayer of surviving.
