Livvi’s story is told in parallel with the stories of a Boston photographer named Micah and a Long Island housewife named AnnaLee. One of them is defined by a stunning act of heroism, the other by a moment of weakness regretted for a lifetime. Micah, AnnaLee and Livvi have never met, but their lives are connected through an extraordinary mystery. A web of hidden truths that exposes the unexpected ways in which we protect, and betray, the people we love.
