Rafael Ward is a historian. His job is to destroy artifacts of the past, to eliminate evidence of a world before his own. A world that once believed in gods and monsters. But when he meets MacKenzie, a notorious terrorist and Believer, he soon finds himself embroiled in her quest for the Vase of Soissons, Dark Age relic foretold to return faith to the world. When his government turns on him, Ward’s only chance is to trust MacKenzie and find the Vase before their enemies do. But, it turns out, the Vase might not be what she thought after all, and the truth could destroy everything.
