I found it in my school library when I was in grade 4? (I think). I knew the show but not the books and decided that if I was going to read a book it would be this one. I got hooked, read the series AND the prequel, then moved on to Guardians of Ga'Hoole (which my school library also had like 12 books of). I binged that series in like 2 weeks, there was a point where I read a book a day. It was insane because I'd never had an interest in reading and suddenly I was addicted.
