A move to a small seaside town gives Billie a chance at a new life and new love - until the undertow the past pulls her toward a shocking secret.

When sixteen-year-old Billie Paradise unexpectedly inherits her grandmother’s house, it couldn’t come at a better time. With her stepdad abroad and her mom starting to lose it, moving from their cramped London apartment to an old house by the sea seems serendipitous. Maybe Billie, as she navigates the small-town social scene and falls for a certain intriguing older boy, can even find the father she never met. But her mom’s remote childhood home, which she left in haste before Billie was born, harbors hints of suspicious long-ago deaths and family secrets. As Billie’s story unfolds, flowing back and forth in time and through alternate points of view, it becomes clear that while people may die, the past lives forever.
