I really liked de Bodard's short stories and decided to try this fantasy / mystery book as well. It was fascinating, but quite not as good as the short stories. Aztec names and a foreign mythology made this both interesting and hard to read. If you want to try something new, this is the book for you. I don't yet know if I'll read the 2 other Obsidian and blood -books. Perhaps, if there is nothing more interesting to read.
