The novels we include in our boxes are categorized as Young Adult, and as such are recommended for ages 14 and up. It largely depends on the maturity level of the reader. Some children younger than 14 years of age would probably love OwlCrate and the books we select. We recommend taking a look at our Past Boxes page, to see everything we've mailed in the past. Hopefully that will give a better idea if our service is right for the reader you have in mind!
If you are concerned about a certain theme or book, we are always here to answer any questions you may have.
