Kindle Chinese Books for Kids that Love to Read!

I’m trying to get my kids to read more Chinese fun books (from Grade 1 up to Grade 10). They love to read ENGLISH books on the Ipad and Kindle, but having a hard time finding Chinese books (Traditional text strongly preferred). Any ideas on where to get Chinese books in .MOBI or .EPUB format for kids? Having a hard time finding anything…things like Harry Potter, Percy Jackson, etc. are a good start but then I’m sure there is tons of good Chinese only literature out there as well…I just can’t find it.

Publishers here aren’t interested in ebooks, sadly. They will doubtlessly regret it in the future.
