From the New York Times–bestselling author of the Lemoncello series comes Ms. Pennypickle’s next laugh-out-loud puzzle adventure! When she launches a reality-show contest for a million-dollar prize, two kids must outwit cheaters and solve her epic riddles to win.

When Ethan and Benji won Ms. Pennypickle's epic quest, they weren't supposed to tell anyone...so when Benji makes a viral video, Ms. Pennypickle is in trouble! Luckily, her head of advertising, Jack has a plan! It's time to create a Pennypickle reality show and give a few teams a chance to follow in Benji's footsteps and win the ultimate prize. Jack's son, Jackson is a master puzzler...and when one of the contestants, Hope, is without a team member, Jackson steps in to help her race across the country. 

With Hope's mom as their driver, the pair solve riddles, anagrams, word scrambles, and more as they cross the USA hitting sights like a giant Paul Bunyon statue and the St. Louis Gateway arch. But as the two learn to work together and solve the puzzles...another team is determined to cheat their way to the finish. Can Jackson and Hope find their way to a triumph fair and square?
