The novel was released in paperback on September 23, 2014 through Quirk Books and is set in ORSK, an IKEA-esque store that has been experiencing supernatural phenomena.

[1][2] The novel follows a group of people—store manager Basil, and employees Amy and Ruth Anne—who stay overnight at ORSK to investigate strange acts of vandalism.

During the séance, they make contact with Warden Worth, who possesses Carl and informs everyone that he will take them into his "Beehive" and cure them of their mental illnesses.

She returns upon realizing that she is the others' only hope of escape, and that running away would mean quitting, which would prove Worth correct in his assessment of her failings.

Amy is unsuccessful in rescuing Ruth Anne before the woman commits suicide, but frees Basil and helps him keep sane by talking to him about his sister, for whom he is a caregiver.

The book ends with an advertisement stating that Planet Baby will hold a 24-hour sale, allowing patrons to remain in the store overnight.
