"Diane was given three months to live, until one day, after much prayer, the cancer just disappeared. After moving into a charming new cottage in Marble Cove, where she spent many summers when her kids were young, she becomes friends with her neighbors, except for Beverly, who at first politely rebuffs her attempt at friendship. The women wrestle with what their strange bond means and why God has saved them and given them a second chance at life. As they develop deep and life-changing friendships, they uncover a mystery at the Orlean Point Lighthouse. The decommissioned lighthouse inexplicably flashes beams of light as they discover a man caught in the tide. It takes all four women, even reluctant Beverly, to save him, and they begin to recognize their unique calling to help others" -- Publisher website.
