Doctor Proctor's Fart Powder

Doctor Proctor's Fart Powder is indeed a children's book written by Jo Nesbø, a bestselling Norwegian author known for his mystery novels. Here is a summary of the book:

Eleven-year-old Nilly moves to a new neighborhood and quickly befriends an eccentric professor named Doctor Proctor, who is known for inventing strange potions and powders. Nilly also becomes friends with brainy Lisa, who is often teased by the mischievous twins, Truls and Trym. Together, Nilly, Lisa, and Doctor Proctor embark on hilarious and magical adventures.

The trio assists Doctor Proctor in developing a new invention called fart powder, which, as the name suggests, makes people fart. Nilly and Lisa start selling the powder at school and become very popular. They also get their revenge on Truls and Trym by giving them an extra-strength dose of fart powder that launches them into a tree.

However, things take a more adventurous turn when Doctor Proctor creates an industrial-strength version of the fart powder that can send people to outer space. Nilly, Lisa, and Doctor Proctor must protect their invention from falling into the wrong hands as their neighbors attempt to acquire the powerful powder for nefarious purposes.

Doctor Proctor's Fart Powder combines magic, wit, and bathroom humor to create a funny and entertaining story. It shares the spirit of authors like Roald Dahl and Lemony Snicket, offering a delightful blend of humor, adventure, and absurdity that will captivate readers of all ages. Jo Nesbø demonstrates his ability to keep readers on the edge of their seats while making them laugh out loud.
