From two-time Olympic bronze medalists Maia and Alex Shibutani comes a fun-filled, fast-paced middle-grade mystery set at the Tokyo Olympics.

Andy and Mika are going to Tokyo!

The Kudo Kids have never been to Japan before, so they can't believe they get to attend the Summer Olympics there. The siblings plan to eat tons of delicious Japanese food, watch every event they can, and win a super-popular new game called OlympiFan.

Developed by a mysterious former medalist, OlympiFan brings players together from all over the world to search Tokyo for virtual medals and clues to the creator's identity. Andy loves puzzles, and he's determined to crack this one, especially since the winning team will get to be beta testers for the Masked Medalist's future games!

Mika wants to find as many clues as she can, but she also has a secret goal of her own--one that could get her into big trouble. But when someone sabotages the game, the Kudo Kids have an even bigger mystery to solve than the Masked Medalist's identity. If they want to capture the gold, Mika and Andy have to figure out who's trying to stop their team before someone beats them to the grand prize!
