Sophie and Joseph Argenton have survived the impossible… for now. But their escape from Northwood is short-lived. The sinister shadow that haunted their ancestral home survived, and has attached itself to Joseph's young cousin. Desperate, they travel to meet her father at Kensington, a long-abandoned mansion overlooking a dead town. The house offers a small hope: its original owner had dedicated her life to researching the monster that now possesses Elise. There's a chance that here they will find a way to kill the creature without harming the girl. But Kensington has its own dangers, and once it has Sophie and Joseph within its grasp, it may never let them leave. Trapped inside the ancient building's collapsing walls, Sophie and Joseph are forced to confront the horrors that hide within. Shrouded figures stalk them from the shadows. Whispers echo through the night. Unmarked graves dot the property. And the dead are not as restful as they seem…
