This finale—as in final, last, ultimate, never-to-be-another—wraps up two of Green’s popular and successful fantasy series, the Secret Histories (Moonbreaker, 2017, etc.) and the Nightside (The Bride Wore Black Leather, 2012, etc.).
Neither series needs much introduction. The Secret Histories are all about the Droods (less a family than a small nation), whose self-appointed mission is to keep reality safe from marauding supernatural creatures; the Nightside (where it’s always 3 a.m. and pretty much anything goes—the weirder and more violent the better) doesn’t want to control anything, especially itself. For centuries, solemn Pacts and Agreements have kept the Nightside unchanging and the Droods out. But now, impossibly, the Nightside’s boundaries have changed, and something very, very scary is approaching—so scary that even the gods have abandoned the place. Does the prospect of a showdown between hordes of control-freak Droods in impenetrable armor and the immovable, laissez-faire, monster-filled Nightside appeal? Of course it does, and luckily Green’s eager to tell us all about it. What’s really going on, and why? Nobody knows, least of all John Taylor, the man known as Walker (he runs the Nightside), or the Nightside’s mysterious Authorities. The Drood Matriarch, meanwhile, orders shamus Eddie Drood and his lover/sidekick, badass witch Molly Metcalf, to investigate while secretly preparing for war, if necessary to the death—of the Nightside, that is; the Droods always win. Before the grand face-off, though, Green showcases, often hilariously, most if not all of the weird beings and doings you might have missed in the previous books.
A splendid riddle wrapped in a mystery inside an enigma, conveyed with trademark wisecracking humor, and carried out with maximum bloodshed and mayhem. In a word, irresistible.
