Craig Novian and his small construction crew take a late-night contract job inside Mercy House expecting nothing worse than a long night repairing old systems in an abandoned hospice building nobody in town likes talking about. The building should have been empty. Instead, Mercy House is still running. Beneath the collapsing structure lies a maze of flooded tunnels, sealed patient wards, and underground archives where grief has been preserved long after death should have ended it. The deeper Craig and the others descend beneath the property, the harder it becomes to separate memory from reality. Hallways shift. Voices return through dead phones. Rooms rebuild themselves from loss, guilt, and unfinished attachment. Then the storm arrives. Roads disappear. Flood tunnels collapse. And Mercy House begins trying to keep them. Because the worst part of the building is not what waits underground. It is how easily Mercy House learns what people desperately want back. Mercy House is a psychological supernatural horror novel about grief, memory, survival, and the terrifying cost of refusing to let go.
