The $3 time machine strikes again in this third and final installment in the series perfect for fans who love funny, unexpected adventures and wacky plot twists from best-selling author Dustin Brady.

Professor Snellenburg is a mysterious man. What’s the real story behind his time machine? What does the villainous Queen want with him? And where is he now?

To find the professor, Elsa and Liam will need to start digging up answers to these long-buried secrets. Their search starts with the Voynich Manuscript—a book from the Middle Ages that puzzles historians and codebreakers to this day. They’ll travel to an alternate dimension, where they’ll meet Dwayne “The Rock” Johnson (the geologist, not the wrestler) and discover the shocking origin of time slime. Finally, with the help of the World’s Worst Time Machine, they’ll attempt a journey to the very center of time.

As the kids close in on the answers they’ve been seeking, their world begins turning upside down. Who’s the hero of this story? Who’s the villain? And what happens when you find out that everything you thought you knew was a lie?

With over two million books sold, Dustin Brady has cracked the code for keeping kids reading. Short chapters, zany twists, and unforgettable characters hook even the most reluctant readers, while the blend of real history and hilarious storytelling makes this series both fun and fresh. Ideal for fans of time-travel adventures, wacky humor, and page-turning mysteries, the World’s Worst Time Machine series will have readers racing to the last page.
