Gaming-obsessed brothers Max and Liam are back, and they're in for another adventure of CATASTROPHIC proportions. It all goes wrong when a rogue app transforms them from human boys into fleas, and it only gets worse from there. The speed a cheetah can run and the acidity of pigeon poo have never been more important. A laugh out loud, fast-paced adventure full of comic-style illustrations that bring the action to life and will absorb even the most reluctant of readers.
