Years ago, yellow fever gripped the small lakeside town of Prosper, Arkansas. At the height of that summer swelter, in the wake of an unexpected storm, the dam failed and the valley flooded—drowning the town and everyone trapped inside.

The secrets of old Prosper drowned with them.

Now, decades later, when a mysterious locked box is pulled from the depths of the lake, three descendants of that long-ago tragedy are hurled into another feverish summer. Cassie: the reclusive sole witness to an impossible horror no one believes. Lark: a wide-eyed dreamer haunted by bizarre visions. June: caught between longing for a fresh start and bearing witness to the ghosts of the past. Bound together, all three must contend with their home’s complex history—and with the ruins of the town lost far beneath the troubled water.

At turns haunting and breathtaking, Cicadas Sing of Summer Graves explores legacies of love, family, and the ghostly imprint grief leaves behind.
