Zach & Zoe Mysteries Books in Order

The Zach and Zoe Mysteries are Mike Lupica's lightest, youngest sports books, and that is the fun of them. These are chapter-book mysteries built around eight-year-old twins Zach and Zoe Walker, two kids who love sports almost as much as they love poking around a puzzle. The books keep the stakes friendly, but they still give readers the pleasure of clues, suspects, and small discoveries.

What makes the series click is the mix. One book gives you a missing signed baseball. Another gives you a restored basketball court, a deflated football, a mystery soccer jersey, a lost lucky necklace at a hockey arena, or trouble on a class trip to Cooperstown. The sports keep changing, which helps the series stay lively.

Zach and Zoe are the constant.

They make a good pair because they are not identical in temperament. They notice different things, ask different questions, and work better together than apart. That keeps the mystery element moving without making the books feel too heavy for young readers. The cases are built to be solved by attention, curiosity, and a little persistence, not by danger.

There is also a nice family warmth running through the series. These books feel lived in. School, siblings, local games, special sports experiences, all of it sits inside an everyday world kids can recognize. Even when Zach and Zoe end up near big settings like the Bruins or the Hall of Fame, the tone stays approachable.

Start with The Missing Baseball, then read forward. The books are short, clear, and easy to hand to a young reader who likes both sports and mysteries but is not ready for anything too intense. This is Lupica keeping the heart of his sports fiction while dialing everything down to a smart, cheerful level.
