@Logan_Brokenspark What?! It literally gets SOOOO much better! You have no idea how awesome the series is! Each of the books is great on its own, and it all explores different moral themes in potential societies. When the final book happens, it explains why everything happened in the first place, and it is mind blowing. Ugh, I wish I could read it again for the first time, they were that good.
There might be some curse words, but I don't remember anything else. Definitely not explicit in any way.
The 3rd one, the one with Pendragon in a plane on the cover, is one of my favorite ones!
