Last we heard from Samuel Johnson, he's foiled Mrs. Abernathy's plan to open the portal for the Great Malevolence and his demon army to invade the world. Now Samuel, with all that craziness behind him, is trying to psych himself up and ask a girl out, though he can't see quite well so instead, he's asking a letterbox if she wants to go on a date.
Samuel may have gone back to his normal life, but he's not forgotten. Oh no. Far from it. Down in the Infernals, Mrs. Abernathy, who has lost all her clout with her fellow demons, is stewing and plotting revenge.  She is going to drag Samuel down to her territory this time. But have no fear, Samuel has his loyal dachshund Boswell, and a new cast of helpers: two cops, an ice-cream man and a traveling troupe of elves (who are really dwarfs).
Just like The Gates, The Infernals will delight readers who are looking for funny, adventure, wit, and some great friendships.  The characters are just priceless, and Terry Pratchett fans will be glad to see the same quality footnotes from Connolly.  This continues to be a great series for teens who are looking for something smarter than the usual fare.
