Mark Genevich is a narcoleptic detective operating out of his mom's apartment in South Boston. In his debut, The Little Sleep, Genevich is hired to identify the girl in a couple of photos but he can't remember who gave him the job because he was asleep at the time. No Sleep Till Wonderland sees Genevich forced into group therapy by his landlord mother. But soon Genevich is pulled into events over his head—rescuing a child from a burning house, possibly getting a girlfriend—but above all, figuring what happened while he was unconscious.
