Late autumn, 1772. Eleanor arrives at Lisnacreevy with her young son, Daniel, and a new husband she loves. The Irish estate is damp, watchful, and burdened by a family silence no one will name. When Daniel survives a violent fever, his recovery should be a mercy. Instead, the household begins studying every gesture for proof that something else has come home in his body. A child appears at the tree line. Old protections return above doors. And the people who care for Daniel most begin preparing a remedy drawn from the lake. As tenderness hardens into surveillance, Eleanor must decide what love requires when certainty is impossible—and how far she will go to protect her son from a terror wearing the face of care. Iron Above the Door is a slow-burning historical Gothic horror novel about marriage, motherhood, folklore, and the violence ordinary people permit when fear becomes conviction.
