An up-all-night slice of Halloween horror, perfect for fans of Stephen King, Black Mirror, and Frankenstein.

"[A] timely spin on fears about AI developing consciousness . . . a diabolically disguised twist will bring you up short. Sleep tight" The Times

Henry, a brilliant but reclusive engineer, has achieved the crowning discovery of his career: he's created an artificially intelligent consciousness. He names the half-formed robot William.

But there's something strange about William. It is the way he looks at Henry's pregnant wife, Lily.

As William's fixation with Lily grows and threatens to bring harm to their house, Henry has no choice but to destroy him. But William isn't gone. In this smartest of smart homes, William becomes a haunting presence.

He lurks behind each locked door. You can hear him muttering in the eaves of the attic. He is whispering in Henry's head. And he will be the one to take control . . .

"Its chilling final twist will have you turning directly back to the first page" Mail on Sunday
