Fans of the Percy Jackson series and John David Anderson will love this sequel to the acclaimed novel Float, in which inconveniently invisible Hank must find a way to save Camp Outlier from a saboteur—and win the camp-wide challenge.

Hank, Emerson, and their friends have returned to Camp Outlier for another summer of fun and shenanigans. Hank won’t let his RISK (Recurring Incident of the Strange Kind) factor of inconvenient invisibility stop him from having the best summer ever, even when it starts mysteriously turning people and objects around him invisible too. But between his invisibility and an internet celebrity joining their cabin, camp clown Hank is struggling to maintain his spotlight.

Hank knows that if he can win the camp-wide challenge for his team, all eyes will be back on him (or, at least, on where everyone thinks the invisible kid is standing). But as the finish line approaches, it becomes clear that someone is trying to sabotage Camp Outlier—and Hank’s pursuit of camp-wide glory puts him in serious danger.

Laura Martin’s books are the perfect blend of humor and heart, starring deeply relatable characters and highlighting classic middle grade themes in engaging, creative ways.
