A House at the Bottom of the Lake by Josh Malerman

The story begins: young lovers, anxious to connect, agree to a first date. At seventeen, James and Amelia can feel the rest of their lives beginning. It feels like they have this summer and this summer alone to experience the extraordinary. They didn’t expect to find it in a house at the bottom of a lake. The house is cold and dark, but it’s also their own. Yet how to explain the furnishings? The upkeep? The icy sense of something living there still? Caution be damned, until being carefree becomes dangerous. Because now the teens must decide: swim deeper into the house—all the while falling deeper in love—or return to the surface, and to safety, to sanity? Whatever they do, they will never be able to turn their backs on what they discovered together. And what they learned: Just because a house is empty, doesn’t mean nobody’s home.
