Every newly independent reader will be rolling on the floor--and has a chance to solve the mystery--in this wildly wacky mash-up of chapter book and graphic novel, with art on every page, interactive seek-and-find elements, and more! In this first book of the series, fourth-grade detective Logan Lang is facing the biggest case of her career. Someone--or something--is stealing everything that kids love. Toys! The amusement park carousel! Even the school playground! All of them sucked underground without a trace. Logan will have to team up with her longtime nemesis and super cop wannabe Gustavo Muchomacho if she wants to stop this subterranean scoundrel. With her serious doodling skills and his arsenal of high-tech sky mustaches, they'll race against the clock to unearth a master criminal. Bonus backmatter is loaded with extra puzzles, word jumbles, instructions for drawing suspects, and doodle activities! - from Amzon
