After Mop and crew’s discoveries on Earth, the Prodryans are massed to attack, and the Alliance is falling apart. Mop’s next mission: Tuxatl, the only planet in the galaxy the Prodryans fear, seeking a weapon that can win the war. As usual, what she finds isn’t what she expected: a legendary lost warrior and the Jynx, an intelligent race hiding dark secrets. There is a weapon—but what do you do if using it makes you just as bad as your enemy? While there’s plenty of humor in this installment of Janitors of the Post-Apocalypse (after Terminal Uprising, 2019), it’s not a funny book. Characters face deep personal threats and challenges to their status quo and struggle with significant ethical quandaries; the book achieves impressive emotional depth and moral weight. Hines has a talent for creating interesting aliens, and the Jynx are one of his best yet, with a fascinating culture and backstory. The newest members of Mop’s crew lend some fresh perspectives, and the ending—unexpected as it is—rings true. Hines serves up a satisfying and hopeful conclusion to the series.
