Book 1 Doctor Proctor's Fart Powder by Jo Nesbø

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!)

But when Doctor Proctor creates an industrial-strength version that can send people to outer space, the kids must go to great lengths to protect the invention and keep it out of the hands of their neighbors, who want to use the powder for evil purposes.

In the spirit of Roald Dahl and Lemony Snicket, Doctor Proctor offers a winning combination of humor, adventure, and absurdity that kids (of all ages) will love—proving that Jo Nesbø can keep you on the edge of the seat and make your sides split in equal measure.


Book 2 Bubble in the Bathtub by Jo Nesbø

The Fart Powder was such a successful invention that Doctor Proctor, Nilly, and Lisa couldn’t stop there. Next up: a time-travelling bathtub. You just hop in, lather up the Time Soap, and wish for where you’d like to go. Doctor Proctor has plans for this new invention. You see, he lost his true love years ago, when Juliette Margarine married an evil count. The good Doctor has never quite gotten over this, and he's going back to change it. But when things go wrong, it's up to Nilly and Lisa to travel back in time to right all wrongs and reunite the two lovebirds. Nothing is quite so simple in a Jo Nesbo book. Enter a herd of hippos, a scheming assistant, and Time Soap that keeps going awry, sending Nilly and Lisa to the storming of the Bastille! Fortunately, as in every Jo Nesbo book, the Fart Powder solves everything.

Book 5 Can Doctor Proctor Save Christmas? by Jo Nesbø

Doctor Proctor, Nilly, and Lisa try to save the holidays in this fart-tastically funny adventure from New York Times bestselling author Jo Nesbø.

When the king of Norway sells the rights to Christmas to Mr. Thrane, it looks like the holidays aren’t going to be very merry. Mr. Thrane says that the only people who can celebrate are those who buy 10,000 crowns worth of presents from his department store. For anyone who doesn’t - or can’t - spend that much, it’s no tree, no presents, no carols, and no Christmas pudding.

Dr. Proctor, Nilly, and Lisa aren’t going to take this sitting down! They’re going to find Santa and save Christmas. All they need is a sleigh, flying reindeer, some time travel soap, and, of course, some fart powder!
