When fireman Jimmy McMullen is killed in the line of duty, his wife, Jackie, and ten-year-old son, Charlie, are devastated. Trusting in the healing power of family, Jackie decides to return to her childhood home on Sullivans Island—a place of lush green grasslands, the heady pungency of Lowcountry Pluff mud, and palmetto fronds swaying in gentle ocean winds. Thrilled to have her family back, matriarch Annie Britt promises to make their visit perfect. Over the years, Jackie and Annie, like all mothers and daughters, have had differences of opinion. But her estranged and wise husband, Buster, and her best friend, Deb, are sure to keep Annie in line. She's also got the flirtatious widowed physician next door to keep her distracted. Captivated by the island's natural charms, mother, daughter, and grandson will share a memorable, illuminating summer.
