A 13-year-old boy with an unpredictable power returns to camp for another summer of misadventures in this follow-up to Float (2018). "Inconsistently invisible" Hank can't wait for another summer at pricey Camp Outlier, the one place where he and other RISK kids stigmatized for their uncontrollable abilities, or Recurring Instances of the Strange Kind, can find a sense of belonging. However, his excitement turns to worry when his time-traveling friend appears in the airport bathroom with a tearful warning that Hank is going to die. To make matters worse, a YouTube heartthrob joins their cabin, stealing the center of attention from Hank and making him feel more invisible than ever. On top of that, someone is attempting to sabotage their camp. At this camp of misfits, the cast of characters is predominantly White, with race largely indicated through clumsy, stereotypical descriptors ("gingerbread-colored skin," "almond-shaped eyes"). Hank flirts constantly with girl campers, referring to them as "ladies" and commenting on their attractiveness regardless of their interest in him, behavior in keeping with the book's overall presentation of gender relations: "I'd had my sights set on her at the beginning of camp the summer before, but after I'd realized that Emerson did too, I'd done the gentlemanly thing and stepped back. Besides, Kristy was an intriguing challenge, and I liked intriguing challenges." Not unlike Hank's flirtation, the story's lesson about technology addiction lacks subtlety and nuance. A sequel filled with boys-will-be-boys sensibilities. (author's note) (Fantasy. 8-12) Copyright (c) Kirkus Reviews, used with permission.
