Childless heiress Abigail Adams Longley and three other widows bond over a Renaissance masterpiece in Florence, Italy, and find love, friendship and joy in their joint venture to open an art gallery at the Longley mansion in Lobster Cove, Maine. Since the death of her husband, Abigail has been lonely and drifting in a house that's too big and a town that's too small. When she literally runs into sexy widower and whale-watching excursion captain Tack Garrity on the dock, she's entranced by his adorable five-year-old daughter. But will Tack, who has harbored a secret crush on Abigail for almost two decades, be able to capture her heart? A secret pact her husband made with Tack could either tear them apart or bring them closer together and change their lives forever.
