The Penfurzy Rebel Bicycle Club saves not only the island, but maybe the whole world in this third video game–inspired episode following Rebel Bicycle Club (2023).The club-which includes friends Demelza and Nessa, Captain Honkers the goose, and Mr. Calenick, a pickled medieval knight with a detachable head-gains a new member when Jack arrives on the island (established in previous entries as being in Cornwall) with his white dad and Haitian mom as part of a traveling carnival with several secrets and a rusty old bicycle in serious need of proper tricking out. One of the secrets, it turns out, is that Jack is a descendant of a certain legendary Jack from folklore, and another is that there are giants in caverns below Penfurzy, rendered harmless (for now) by a sleeping spell that is in desperate need of being renewed if they are not to rise and wreak havoc. Can the club members, wielding foam swords and riding wheeled steeds with names like Neon Justice II and Rogue Avenger, find a way into the giants' cavern before they wake up? Created in conjunction with the Knights and Bikes video game, this volume features both blocky illustrations that reflect the game's distinctive graphics and a pacey plotline festooned with obstacles, sudden reversals of fortune, magical helpers, daring exploits, and comical banter.Brisk, bold, and buoyant.
