Adrian and Nova, two teen superheroes, have a lot in common: a problematic hidden identity, a secret plan to avenge a family member's death, and a growing attraction to each other that is impossible to indulge simply because of who they are. As they navigate these complexities, they also continue their training as Renegades (law enforcement for Gatlon City) and wrestle with the ethics of a new weapon called Agent N, which nullifies superpowers forever. An omniscient narrator alternates between Adrian, aka "Sketch" and "the Sentinel," and Nova, aka "Insomnia" and "Nightmare," parsing out backstories, action, and emotions in a way that will hook readers. It's helpful to have read Renegades? (2017) before beginning this bridge book, and a promised character list will help keep their multiple identities aligned. This enticing mix of superhero adventures and budding love story also tackles hefty ethical issues, and Meyer masterfully manipulates plot and characters to send readers racing for the last page and regret reaching it, especially when they're met by its suspenseful cliff-hanger.

This sequel to Renegades finds Nova, a superpowered -prodigy,- firmly embedded as a double agent among the Renegades (a powerful band of superheroes), covertly working toward destroying them and reviving the defeated Anarchists (a team of villains). Meanwhile, her Renegade teammate Adrian flounders, torn between the Renegade code and the unconstrained power he wields as the vigilante Sentinel, his secret identity. A new weapon capable of permanently removing a prodigy-s powers offers new possibilities for both Renegades and Anarchists-and for unexpected common ground between Adrian and Nova. Meyer is fantastic with superpowers, and the best moments in the book involve ingenious or breathtaking displays of ability, as well as entertaining hints of a centuries-long prodigy history. Much of the plot, however, revolves around thin quests for empowered objects, while the narrowed focus on Adrian and Nova-s deepening romance undercuts both the powers that make them interesting and the larger cast of characters. Following an exhilarating opening, the middle section treads water, never quite capturing the novelty and urgency of the first book, but the page-turner conclusion will leave readers eager for the final installment. Ages 12-up. (Nov.)
