I don't read much science fiction or fantasy, but this series caught my eye because I do like historical fiction (whether fantasy, mystery, whatever...) set in unusual times/places. Don't get me wrong - I also like the more common ancient Egypt, English Regency, etc. as settings, but it's also fun to find something set in Aztec times. And this also sort of crosses over into the mystery genre as well...

Anyway, Servant of the Underworld is the first in the Obsidian and Blood series by Aliette de Bodard. I've read all (I think) of the titles in this series and quite liked them. Servant has recently dropped to $2.99 at Kindle US.

Spoiler:

The first book in the critically acclaimed Obsidian and Blood trilogy:

Year One-Knife, Tenochtitlan the capital of the Aztecs. Human sacrifice and the magic of the living blood are the only things keeping the sun in the sky and the earth fertile.

A Priestess disappears from an empty room drenched in blood. It should be a usual investigation for Acatl, High Priest of the Dead--except that his estranged brother is involved, and the the more he digs, the deeper he is drawn into the political and magical intrigues of noblemen, soldiers, and priests-and of the gods themselves...
