In Bialys’ third series installment, the author performs a narrative victory lap, securing his trilogy a permanent place on his readers’ shelves. The tale expands the cast but maintains an excellent pace and a perfect balance between comedy and drama. Self-doubt torments the principal characters as much as any vampire cat might; indeed, Ms. Creante reminds Makenna, “you have yet to win a battle all on your own.” Later, in the Under Realms, a being named Orsin feeds Stephen from the tree of knowledge, and the boy experiences a vision in which Sam and Makenna get married as adults. Stephen and Sam nearly have a falling out over this possible future, and Bialys offers a potent illustration of young love. Seaton eventually tempts Makenna with a vision of herself as the most popular, graceful student at school (even the obnoxious Heather Stern worships her); the vision could be reality—if only she’ll give up the twins. Fluffy, in the guise of Michael, provides comedic relief as he struggles with being human. Bialys also offers plenty of quick jokes for adult fans, as when Marigold threatens to withhold DuGaiman’s tickets to a Celine Dion show. Such consistently entertaining details keep the story fresh and buoyant despite the darker themes. The sparkling prose never bogs down, and it’s a joy to meet creations with clever names, such as Ms. Judged. In the end, Virago’s adventure ably delivers a fine message of selflessness.

A nuanced and grand fantasy-series finale.
