Mal, a fearless girl, needs adventure, and her friends are right there with her: Lenna, a dreamer whose family underestimates her every day. Tok and Chug, brothers who love to build stuff (Tok) and smash stuff (Chug). They’re best friends, and in a town whose grown-ups value safety over bravery and fitting in over standing out, they’re the bad apples. On their journey across the Overworld, they discover wonders they’ve never dreamed of and dangers they’ve never imagined. To save the day, they’ll have to prove they’re more than bad apples. They’re the Mob Squad!
