The final volume in the Obsidian and Blood trilogy. In and of itself it's a nicely fantastical murder-mystery, if in places a touch repetitive (Copal incense! Always with the copal incense) and with a slightly abrupt conclusion. As a way to finish off the series it's stronger: the characters are fleshed out more (including, importantly, the previously wasted Mihmatini) and the plotting and politics are convoluted enough to keep things interesting without becoming overwhelming. There's a marked improvement across all three installments, which makes the current buzz surrounding de Bodard's newest book very easy to believe. As if my unread pile wasn't big enough already.
