It's hard to rate this book. It was really, really good...the world building is amazing, the writing is to die for, the characters are intriguing...but it didn't really feel like it had any soul. All the technical pieces were there, but it was lacking the emotional oomph that would have really tied it together and made it an AMAZING book.
Also, the gratuitous descriptions of gross things really got to me about 2/3 of the the way through the book. It's like GRRM but worse. The details served a purpose often, but sometimes it was just too much. I think he lost me when the whole thing with Nazca went down...too much ew.
So while I regret that I will never meet Sabetha, I won't be continuing with this series.
