It is the last summer that Marietta "Mamaw" Muir and her three "summer girls" will ever spend at their beloved Sea Breeze before it is sold. As the end draws near, Mamaw and half-sisters Dora, Carson, and Harper struggle to find new places in the world.

Harper intended to stay only a weekend, but a rift with her wealthy, influential mother left her without a home. Free from her mother's tyranny and encouraged by her family on Sullivan's Island, Harper has at last discovered her talents and independent spirit. Now, the historic beach house's fate hinges on her courage to decide the course of her own life. To do so, she must recognize her newfound strengths and accept love fully into her life--of her family, of the lowcountry, and, most of all, of ex-Marine Taylor McClellan, the wounded warrior who has claimed her heart.
