14 Must-Read Mystery Books for Tweens

by Jennifer Garry

One of my favorite things about the tween age is that one minute, kids in this age group feel ready to take on Serious Things, and the next, you might catch them role-playing in dress-up (that they will tell you is definitely not dress-up). They dream of big adventures, important jobs, and starring roles, and they’re energized by stories of kids doing those very things.

When I was a tween, I loved reading mysteries because they combine all those things. They require clever protagonists who piece together clues while taking on something big and bad — and getting home in time for dinner. I found mystery stories exciting and empowering.

If you have a young reader in your life who likes suspense and deciphering clues (and maybe a little snooping), these 14 books will be a hit.
