Mystery novels for tweens

mysteries for middle grade readers
Posted on May 20, 2025

I talk a lot about mystery novels for tweens.

Whether I’m at school visits or literary festivals or on the Your Kid’s Next Read podcast, it’s a subject close to my heart – probably because there’s usually a mystery, if not at the heart, then not far from it in most of my books.

I’ve always loved reading mysteries – to this day – and I love writing them.

My Maven & Reeve novels are detective stories set in a world of knights and castles.

The First Summer of Callie McGee and Willow Bright’s Secret Plot are cosy mysteries wrapped in coming-of-age stories.

Danger Road, coming in July, features two brothers trying to solve a cold-case mystery that comes a little too close to home.

Even my fantasy adventure series, The Mapmaker Chronicles and The Ateban Cipher, hold mysteries at their hearts – because curiosity drives my writing and nothing drives a story better than a big question.

And, if the number of requests for ‘mystery novels’ for tweens in the Your Kid’s Next Read community is anything to go by, I’m not alone in my obsession.

Megan Daley and I recently had a discussion about the enduring appeal of mystery stories in this podcast episode, and it was at that point that I realised that a) not only did I not have an updated list of terrific mystery novels for readers 9-14 but b) I didn’t have a list here on my site at all.

Over the years I’ve written lots of different book lists full of terrific mystery reads (see some of them here) for other people’s websites and blogs, but not one for my own.

I know.

Anyway, I’m rectifying that here with a list of books that are either recommended over and over in the Your Kid’s Next Read community, are recommended over and over by Megan and/or I, or are new and exciting and will not doubt be recommended over and over in the months and years to come.

You might need a cup of tea for this one because it’s not going to be a short list.
