100 years ago, yellow fever gripped the small lakeside town of Prosper, Arkansas. Then the dam broke—drowning the town and everyone trapped inside. It wasn’t an accident. Now three young women find themselves drawn to the land. Cassie: terrified to go near the water ever since she witnessed an impossible drowning. Lark: returning to her childhood home to clean out her father’s houseboat after his breakdown. June: caught between longing for a fresh start and bearing witness to the ghosts of the past. Their paths grow increasingly intertwined. Forced to right old wrongs, touch forbidden love, and uncover buried secrets, each woman must contend with her home’s complex legacy…and with the ruins of the town lurking far beneath the watchful water.
