Silver on the Road, by Laura Anne Gilman
Isobel is turning 16 and has to decide if she wants to work for the boss or leave the Territory, a reimagined American West full of magic. She has grown up in a saloon, where the Devil lets you gamble at the tables, but is willing to make a bargain if desired. And the Devil always keeps his word and honors his bargains. Isobel decides to stay, but instead is sent out on the road on horseback with mentor Gabriel to learn the Territory and to become the Devil’s Left Hand, a job that doesn’t come with a manual. Isobel and Gabriel encounter talking animals, a traveling magician, shamans, terrifying supernatural winds, and small towns completely empty of people. Young as she is, Isobel needs to take responsibility and find out what is going on in the Territory. A sequel, The Cold Eye, is being published in January, and I’m intrigued to find out what Isobel will encounter next.
