Psychological horror meets cyber noir in this delicious one-sitting read—a haunted house story in which the haunting is by AI.

Henry is a brilliant engineer who, after untold hours spent in his home lab, has achieved the breakthrough of his career—he’s created an artificially intelligent consciousness. He calls the half-formed robot William.

No one knows about William. Henry’s agoraphobia keeps him inside the house, and his fixation on his project keeps him up in the attic, away from everyone, including his pregnant wife, Lily.

When Lily’s coworkers show up, wanting to finally meet Henry and see the new house—the smartest of smart homes—Henry decides to introduce them to William, and things go from strange to much worse. Soon Henry and Lily discover the security upgrades intended to keep danger out of the house are even better at locking it in.
