Join the Club!

by David A. Adler

Like Strawberry's crew, Cam and her friends solve problems together through collaboration and quick thinking, but Adler adds a mystery-solving element that gives the friendship dynamics a purpose beyond just hanging out. The illustrated chapter-book format and ensemble cast of kids working through conflicts mirrors what made Join the Club! so engaging, while introducing your reader to the detective-story genre in an accessible way.

by Margot R. Becker

This is the original friendship-and-club book that influenced countless series after it. What Martin does brilliantly is show how a group with different personalities actually *needs* those differences to function—the conflict isn't about whether the club should exist, but how to make it work for everyone. It's a more sophisticated take on the same core idea that drove Strawberry's story.

by Beverly Cleary

Cleary's Ramona books predate Join the Club! by decades (1968), but they're essential reading for understanding how chapter books capture the genuine social chaos of childhood. Where Bryant's book focuses on club-building harmony, Cleary shows the messier reality of how kids actually navigate friendships—Ramona causes problems without meaning to, and that's where the real comedy and heart live. It's a different era's approach to the same age group.

by Katherine Applegate

This is my surprise pick—it's still about community and belonging, but told from a gorilla's perspective in a way that makes readers think about what friendship and loyalty really mean. Applegate takes the themes of togetherness that Bryant explores and deepens them with genuine emotional weight and a broader worldview. It won the Newbery, but it's not saccharine; it earns its emotional moments through character work.

by Annie Barrows

Barton's Ivy and Bean books capture that specific magic of two kids becoming instant best friends and immediately getting into schemes together. The friendship feels organic and unforced in a way that complements Strawberry's story—these aren't kids solving problems through discussion, they're kids who just *click* and then figure things out as they go. The illustrations are warm and funny, and the chapter-book pacing keeps things moving.
