There are four books about Timmy and his friends, with a fifth on its way. Originally translated from English and published in Sweden by Bonnier Carlsen, the series has sold to 11 language territories including the US (Penguin Random House).

For fans of the film series Shrek and the Chronicles of Narnia and of Frozen, as well as classic books such as Fantastic Mr. Fox, The Cricket in Times Square, and The Mouse and the Motorcycle, this imaginative and engaging debut middle-grade novel by author/illustrator/animator Henrik Tamm includes plucky animal characters, action-packed adventure, and lush full-color illustrations throughout.

Timmy the cat, his pal Simon the mink, and the pig brothers Jasper and Casper are inventors, and they’re hoping to sell their fabulous new contraption to a local merchant. With high hopes, they haul their machine through the crowded streets of Elyzandrium—and are promptly robbed by a gang of bullies. With the help of two new friends, Alfred, a kindly old toymaker, and Flores, a skilled cat pilot, Timmy and his pals set out to get back what is rightfully theirs. As it turns out, they’re not the only victims of these dastardly criminals. But what can this band of misfits do?

In this action-packed adventure, the intrepid Timmy and his wily friends transform themselves into crime-fighting ninjas—and quite possibly heroes!
