I didn't stop reading this because there was anything bad about the book. It's just that I realized midway through that I've mostly outgrown YA—that doesn't mean I don't still enjoy YA books, but it's usually the ones that lean very dark/mature (almost new adult), or are by favourite authors. 

I would still recommend this for YA readers, however. I loved all the different mythical and cultural elements. The setting felt rich and interesting, too, and it's definitely different from a lot of the YA fantasy books out there.
