The summer before her senior year of high school, Laney Jacobs and her best friend jump from a six-story beachside cliff in an attempt to impress their boyfriends. Laney rose from the water. Her friend did not.

Six years later, when Laney's troubled mother's memoir hits the bestseller list airing the family's destructive secrets, Laney is forced to relive the trauma, this time in the public eye. To escape the scrutiny, she seeks shelter at her estranged grandmother's seaside inn. But she can't reconcile the loving woman with the heartless parent in her mother's book. As she looks for answers, the ex-boyfriend who'd witnessed her darkest days reappears, stirring up both pain and hope.

When her mother's vindictive fans threaten her grandmother's livelihood and the lighthouse Laney has come to love, she turns to the century-old words of a young lighthouse keeper to help her find the courage to move forward. But once truths from the past come to light and old love finds new beginnings, will Laney discover that forgiveness is the only way toward true healing?
