Calvin Reed’s brain does not walk. It zooms.

Calvin notices everything: squeaky cart wheels, purple marker smudges, crooked labels, missing plants, and clues nobody else sees. Most days, his fast brain gets him into trouble for talking too much, asking too many questions, and answering before people finish asking.

But when science fair projects start disappearing from Room 12, Calvin may be the only kid who can solve the mystery.

With help from his patient best friend Maya, a nervous new classmate named Noah, and a very serious principal with a suspicious clipboard, Calvin follows the clues through missing projects, hidden messages, and one very important lesson: being right is not the same as being kind.

Funny, heartfelt, and full of classroom mystery, Calvin Reed and the Brain That Wouldn’t Sit Still is a warm middle grade story about friendship, mistakes, second chances, and learning that a busy brain can be a brilliant brain—especially when it learns how to steer.

Perfect for readers ages 8–12 who love clever mysteries, funny school stories, and unforgettable characters who think a little differently.
