Late one night after an otherwise typical day at the office, Catherine O'Malley, a Boston advertising executive, is attacked on her way home. On the way to the hospital, she has an out-of-body experience and hears her late mother say, "Not your time. Our choices define us. Fix what's wrong. More to do."
When she returns to work and finds a junior associate occupying her office, Catherine turns her mother's advice into action. She ditches the career that drove her to become the poster child for live to work instead of the other way around and moves to the island of Nantucket—a place she fell in love with when Jack, her former boyfriend, flew them there on numerous occasions.
Will Catherine's decision to uproot her life, move to the tiny island, and start over create the peace and happiness she's seeking? Will she reunite with her former love, whose family still resides on the island? Or will it prove to be yet another choice she'll come to regret?
