When his marriage crumbles, Mark Currier takes up residence in the abandoned seaside hotel where he once worked. But he is not alone. Something creeps the dark halls inside Longreave. Something cold and wet that will teach Mark to be human again . . . and to be afraid. For there are other forces waking. In the rat-infested cellar. In the labyrinth of the annex. In the house he shared with his estranged wife, Alice. Old loves and older horrors. Hideous revelations that will tear down the walls between Mark and Alice, or destroy them both.
