When tragedy strikes across the ocean, Ellie Lerner drops everything-her marriage, her job, her life in the Boston suburbs-to travel to London and pick up the pieces of her best friend Lucy’s life. While Lucy’s husband, Greg, retreats into himself, his and Lucy’s eight-year-old daughter, Sophie, has simply stopped speaking. Desperate to help Sophie, Ellie turns to a book that gave her comfort as a child, The Secret Garden. As its story of hurt, magic, and healing blooms around them, so, too, do Lucy’s secrets-some big, some small. Peeling back the layers of her friend’s life, Ellie is forced to confront her own as well: the marriage she left behind, the loss she’d hoped to escape. And suddenly Ellie’s carefully constructed existence is spinning out of control in a chain of events that will transform her life-and the lives of those around her-forever.
