Fluffy sci-fi inflected urban fantasy, where your usual naive young woman stumbles into a world of magic and mystery. In this case, that world is the ability to sense the memories of dead people around powerful objects, as mediated through a cranky old Chinese woman, and pursued by a Glass-wearing tech start-up. There's a nice sense of Seattle as a place and Joanna as an amputee, but mostly things just happen, young women are cutesy and confused in a way that seems very XOJane, and the mystery of the secret world and its war doesn't really go anywhere.
