Sean knows that one disaster tends to leads to another—like when his mother got sick and the cost of the treatment meant they had to move out of their cozy Texas home. As they try to get back on their feet, Sean’s parents send him to stay with his aunt and cousin, Zeke, in Victorvale, Massachusetts—a seaside town that has seen its own share of bad luck, with crumbling houses sitting on an eroding coastline that threatens to fall into the sea. It is into one of these decrepit old mansions that Sean and Zeke, along with their classmate Jenny, venture, looking for a neighbor’s lost cat. Before they can rescue it, though, lightning cracks, the ground rumbles, and the cliffside crumbles….
When Sean and Jenny come to, they find themselves trapped inside a house on its side, half submerged in the ocean, leaning against a sheer wall of rock. Zeke is in a room somewhere below them—one that is filling with water. And as night falls and the storm picks up, they discover there may be something else in the house with them.
Now, the three friends must escape before the cold water—or whatever lurks within it—consumes them.
