An omnibus of Obsidian and Blood collecting the three Acatl novels, Servant of the Underworld, Harbinger of the Storm, and Master of the House of Darts, as well as a brand-new afterword (and all the short stories as an ebook supplement!).

It was published in 2012 by Angry Robot, and is now out of print. ETA: following a snafu, this edition is still for sale on some websites (Kobo for instance). I would strongly prefer if you didn’t buy it, because I don’t actually make any money off that sale…
