In 1935, Kitty and Ogden Milton seem to have it all: good breeding, ample fortune, three beautiful children, and the right social and business connections. When a stunning tragedy rocks their world, Kitty and Ogden stumble…but it would never do for a Milton to fall. Determined to forge ahead, they purchase an idyllic island off the coast of Maine, a summer getaway they can hone to perfection. But as the years pass, their children and grandchildren struggle to reconcile the privileges and responsibilities of life as a Milton with the demands of a rapidly changing world. Told in turns by three Milton women—Kitty, her daughter Joan, and Joan's daughter Evie—The Guest Book is an immersive meditation on family, the secrets they keep, and the lies they tell to protect the ones they love.
