After four years in Hell, Mitchell thinks he’s found a way to escape by going back in time and preventing his death. Inside Hell’s vast bureaucracy, he works as an intern to Septimus in the accounting department. It seems that most souls go to Hell rather than Up There, as the damned call Heaven. Hell is becoming seriously overcrowded and has financial issues. When Mitchell learns that Septimus has possession of the Viciseomater, a pocket-watch–like time-travel device, he unites with almost-girlfriend Medusa and best friends Alfarin, a Viking prince from the year 970, and his girlfriend, Elinor, who died in the Great Fire of London in 1666. The team first lands in New York and checks into the Plaza. Unsurprisingly, things don’t go according to plan, and the group begins to sense that some nasty characters from Hell are after them. Hosie writes with a decidedly wry comic style even as she unfolds her dramatic story. The worst job in Hell, cleaning out the ground-floor toilets, is reserved, for example, for reality TV stars. For all the story’s lightness, she doesn’t ignore the ever present problem of paradox: What happens if these characters succeed in preventing their own deaths?
Just outstanding fun for those who enjoy snarky comedy and suspense. - Kirkus Review
