Set in the same world as Elizabeth Bear's "Steles of the Sky" (which I loved and which broke my heart) trilogy but some time later, and the main setting is the Lotus Kingdoms. The main characters are two rajnis, one young, Mrithuri,, the other middle-aged, Sayeh, and two former warriors, Gage and Dead Man. Gage is a cyborg, a former woman who has lived a long time in their artificial body, while Dead Man formerly was a royal guard of a long-defeated caliphate.
Gage and Dead Man were charged to bring a message from a wizard in Messaline to the Lotus Kingdoms, and are working as guards for a caravan as they travel to their destination. The two rajnis's lands, meanwhile, are under threat from relatives eager to snatch power from the two women.
We follow Gage and Dead Man, mostly, through the admittedly slow-moving book; the two have a long friendship, and their conversations, though spare, show a long, comfortable association between the two.
The two women, meanwhile, are while trying to keep greedy men from taking over their lands, also are dealing with internal threats. Sayeh has given birth late in life, thanks to a goddess' magic, and would do anything to protect her young son. Mrithuri has no desire to marry and cede her power to a man, and has the ability to communicate with animals.
And did I mention there is also a wizard, Tsering, who may or may not be the same Tsering from the first trilogy, and the poet Ummuhan, now elderly, is also at hand for the devolving situation in the Lotus Kingdoms.
The pacing, as I've already mentioned, is slow for much of the book, but it allows Bear to give the reader several small but potent character moments, and get a good grasp of what is at stake if the women are deposed. And then, the quietly building tension explodes into conflict, which will play out over the rest of the trilogy, I imagine.
I loved the slow build story, and particularly loved the characters, and all the little details Bear provided to flesh them out.
By the end of the book, the four main characters have been separated and each will have a role to play over the successive books, which I am eager to read.
