All Anton Seiber, newly-minted Master Thaumaturge, wants is to use his training to support himself out in the world. Well, that and to see the man he loves, Imperial Investigator Camille Lumière, more than once every six months. What he gets instead is an invitation to visit L’Institut D’Ingénierie Technologique in Paris, the foremost research institution for thaumaturgy and the arts of war in the world. It’s an offer he can’t turn down…quite literally. Getting to the Institute is a mess that Anton barely survives, and that’s just the beginning of his troubles. Drawn into a web of lies and betrayals, Anton will have to use every trick he can conjure to survive—and perhaps hand over the most diabolical spell in the world in exchange for saving the life of someone he loves.
