The women of the Novak family are each born with a gift: just once, they can turn back time. Lauren has known since she was fifteen that her mother, Marcella, used hers to save Lauren's father from a deadly car accident, and Marcella has lived in fear ever since of what she can't reverse. Marcella's own mother, Sylvia, is her opposite: a free-spirited iconoclast with a glamorous past she only hints at.
When Lauren's husband takes a job in New York, she moves back into her childhood home in Malibu, hoping to surf with her dad and mend an unspoken rift with her mother. What she doesn't expect is Stone, the love of her youth, home for the first time in ten years since he broke her heart. Now Lauren is weighing every choice that brought her here, and wondering whether one of them should be undone.
