Bestselling Norwegian mystery author Jo Nesbø enters the world of children’s books with Doctor Proctor’s Fart Powder, the first book in this very funny middle-grade series. Filled with magic, wit, and bathroom humor, Doctor Proctor will keep boys and girls laughing until the end. Eleven-year-old Nilly is new to the neighborhood, but he is quick to make friends: Doctor Proctor, an eccentric professor who invents wacky potions and powders; and brainy Lisa, who is always teased by the twin terrors Truls and Trym. All is good farty fun when Nilly and Lisa help Doctor Proctor develop his latest invention, a powder that makes you fart. The powder makes Nilly and Lisa VERY popular at school when they sell it for 50 cents a bag. (And they get revenge on Truls and Trym by giving them an extra-strength dose of fart powder that shoots them up into a tree!)
