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.

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 . . .
