These mystery chapter books for kids have both new and classic fiction books that are funny, diverse, wholesome, and fun. Both boys and girls will enjoy reading these books that are full of adventure.

If you’ve ever searched for books for your kids you know that good books are hard to come by. (There are a lot of strange books out there.) With that being said, there are no perfect books so make sure to read them first to make sure they match up with your family’s values before giving them to your kids.

If your kiddos don’t enjoy reading books they can also listen to audiobooks (my son loves audiobooks). Snag your free Audible trial here!

We love many of the books on this list and a lot of them have been read over and over.
