Harrison is the Monster Detective, a storybook hero. Now he’s in his mid-thirties and spends most of his time not sleeping. Stan became a minor celebrity after being partially eaten by cannibals. Barbara is haunted by the messages carved upon her bones. Greta may or may not be a mass-murdering arsonist. And for some reason, Martin never takes off his sunglasses. Unsurprisingly, no one believes their horrific tales until they are sought out by psychotherapist Dr. Jan Sayer. What happens when these likely-insane outcasts join a support group? Together they must discover which monsters they face are within and which are lurking in plain sight.
