It gives one the idea that there is a very deep and detailed world behind it all, but little clues make me think the author makes up a lot of it off the top of their head instead a full world-plan before hand. The latest installment fought off that feeling, but the mantraps made me wonder. I also wish to find out what is "bloodscale" can't figure out what it comes from or why.
Near the beginning I thought Adeline's death was a sort of early wake up, but he continues with a dark theme. I haven't had many books like that, but seeing as it stays in the background, it can be ignored.
The book seems clever, mostly in conversations, and that probably took the most time to get it just right.
