Ms. Pennypickle's Puzzle Quest -- Chris Grabenstein, Hardcover

From the New York Times bestselling author of the Mr. Lemoncello series comes a race across the country full of rousing riddles and laugh-out-loud humor as two brothers try to solve the million-dollar puzzle of an eccentric genius!

Benjamin and Ethan Broderick don't fit together. Twelve-year-old Ben loves retro arcade games and puzzles, while his older brother would rather play sports and hang out with his friends. The only thing they have in common is how much they resent being forced to go on a summer road trip.

But at the quirky diner where the brothers make their very first stop, they discover a clue leading to a giant puzzle race with a million-dollar prize! Along with five other families, the Brodericks are thrust into a high-stakes competition along the famous Route 66.

Can Ben and Ethan put their heads together--and put aside their differences--to beat out the other families and solve Ms. Pennypickle's ultimate puzzle?
