Zephyr Hollis, vampire rights activist and general do-gooder, has some trouble with the mayor in this alternate Roaring Twenties NYC; Prohibition is in full swing and the city council is about to vote on the legality of a similar intoxicant that vampires use, when tainted bottles start killing vampires in a very unusual way. Also, Zephyr is bound to a djinn, and if she doesn’t start wishing soon Very Bad Things will happen, unless she can convince a different demon to break the bond. I liked all the worldbuilding—which includes a chilling explanation of Zephyr’s unusual immunity to vampirism—and Zephyr’s prickly friendships with a psychic and a reporter, both women struggling to do important things in a world that didn’t want them to be important. I’m hoping for a sequel soon! (There’s a short backstory bit up at Tor for completists.) ( )
