Mississippi, 1927. The groanings are coming.

No town is perfect, but East Cobb comes close. It's a wealthy all-Black Free Town―untouched by white oppression―where ambitious Thea Elliot and her husband plan to make good on their big dreams. Little do they know that the idyllic town teems with ghoulish, walking nightmares . . . that only the women can see.

Marah knows the groanings well. She is one of the carriers―women with the ability to pull traumatic memories from men. Populated by men entirely freed of their pain, East Cobb has flourished, even as the remnants of their memories haunt the town's women. When an unexpected death drives Marah to discover more about her own power, Thea's and Marah's worlds collide. The sisters must confront the rotten core at the heart of East Cobb's prosperity and choose what―and who―will survive the reckoning.

A gripping blend of historical fiction and Southern gothic psychological horror, Our Sister's Keeper is a fierce exploration of Black sisterhood, rage, and resistance.
