The Unspeakable Unknown

“In this sequel to A Problematic Paradox, out-of-school adventures open up opportunities for deepening the lore of the worldbuilding and introduce the idea of a horrific new antagonist. They also allow the text to broach uncomfortable (in a good way) discussions on sources of privilege and murky loyalties, both artfully enough to avoid bogging down the action-oriented plots—which introduce new friends and foes and extensively progress storylines left over from the first book (namely, the fate of Nikola’s father and the identity of the traitor at the school). The well-developed denouement provides solid closure while plot tentacles set up the next story. Lots of fun, packing both wacky humor and meaningful plot movement.” —Kirkus Reviews

“Sappingfield layers some nuance into his well-built, wacky sci-fi world . . . [and] balances it all with plenty of humor, dishing up inventive sci-fi fare with a whopping side of silliness.” —The Horn Book
