A story filled with secrets, isolation, agony, and love, The Devout takes us on a journey into the dark world of the Black Death. Set in the early 1400's, The Devout follows the people of medieval Exmoor, England as they witness the systematic killing of the village's sick by a demonic, cloaked rook creature. Two conflicting avenues emerge to lead them the villagers to salvation, each guided by a brother and sister, Luke and Emery. One avenue is led by Emery, an intelligent woman who serves as the village doctor and mentor to Ann, Luke's daughter. The other avenue falls under the watchful eyes of the town preacher, Brother Luke, who attributes the recent deaths as a punishment from God and directs the people of Exmoor on a journey to find salvation by openly repenting their sins. As Emery and Ann wield the proven practices of science, Emery faces the ultimate test when she must go against her brother and his beliefs to ensure the safety of Exmoor at whatever cost.
