For kids, life can be boring, but Liam and Elsa know how to create their own fun-or so they think. After finding a $3 time machine at a garage sale, Liam uses the machine to summon Thomas Edison for help with his book report. It's not until the time machine sends a different Thomas Edison from the 1930s that chaos ensues. World's Worst Time Machine is the newest series from best-selling children's book author, Dustin Brady. Using his signature style, Brady's laugh-out-loud sense of humor and daring adventure will keep even the most reluctant reader wanting to turn the page.
