When 12-year-old Darren Dudlow tears down his school with his bare hands it’s not just the police who want to talk to him. Enter Marek Masters, 14 yearsold, 19% alien and the most intelligent, Most Wanted ‘Almost Human’ alive.

Genetically-modified teens try to bring down the organisation that made them, in this second action-packed installment in the 21% Monster series. The girl put her hands on her hips, cocked her head and answered: 'My name is Aurora Maria Ash-Valero and I'm here to kick your butt!" Since Darren Devlin and Marek Masters joined forces, there has only been one thing on their minds - taking down XSP, the secret organisation that transformed them into genetically-modified superhumans. Even with 21% monster Darren's incredible strength, and 19% alien Marek's super intelligence, XSP is more than a match for them. But what if there was another survivor of XSP's experiments? A tall, tough, athletic teen girl able to withstand sub-zero temperatures and track potential predators? A girl who's 17% sabre-tooth polar bear, and out for revenge. Two's company, but Three IS UNSTOPPABLE in this high-octane adventure, 21% Monster: Ice Giant.

Fun, fast-paced, high-octane action adventure, 21% Monster is a perfect page-turning series for fans of Alex Rider, Percy Jackson and the MCU generation. For once, 21% monster teenage-boy Darren Devlin thinks he has the upper hand over Xastris, the secret organisation that transformed him into a genetically-modified superhuman. Since joining forces with 19% alien boy Marek Masters, 17% sabre-tooth polar-bear Aurora Valero, and now 16% alien girl Genie, Darren has never been in a stronger position...but neither have Xastris. For they are planning an attack on the world's greatest superpowers, with the fate of millions at stake. Can Darren and the team intercept Operation Serpent Strike...or will Xastris land their deadliest bite yet?
