First Clues: Mysteries for Kids

Thank you for visiting First Clues: Mysteries for Kids, your source for mystery series books for children and young adults.

Select your favorite mystery series from the list on the left. We've also included categories of mini mysteries and minute mysteries, both of which are a terrific way to introduce your child to the world of mystery books. In addition, we have links to our partner site, Games of Mystery, which has a large number of mystery parties available for kids and teens.

To help you decide which mystery series may be most appropriate for your child, we've sorted our mysteries by broad age ranges: New Sleuths (ages 4 to 6), Junior Sleuths (ages 7 to 10), Cadet Sleuths (ages 10 to 12), and Apprentice Sleuths (ages 13 and older).

We also have a number of First Clues Reviews, reviews of books featured on this site written by students giving their unique perspective on the book they read. Where available, reviews found on Mysterious Reviews and Book Trends are also noted.
