For centuries, the Chevaliers de Rouen pledged to fight the monsters that inhabit France until their last breath. In the mid 1800s, Michel-Leon Parisee is the last of his line. The whispering memories of the chevaliers who passed before him offer help but have also driven other chevaliers mad with their constant advice, so Michel-Leon is forced to maintain a careful balance. When an ancient hunger threatens Paris, Michel-Leon must gather every tool he has to fight a terrifying threat that has eluded destruction before.
Constantin Severin is fey kissed, a man who walks the line between the fantastical and the mundane. He is determined to kill the magicman, the monster who destroyed his childhood, and rescue its young victims. In doing so, Constantin is in danger of becoming what he hates most. He needs a chevalier, but Michel-Leon is consumed with his own battle. Constantin must set aside old suspicions and his wandering ways if he is going to bargain for the help he needs.
Together, they can find the strength they need to battle their respective demons. They can learn they don't have to fight alone, but it will take trust. It will take letting down long erected barriers, and it will take love. If they fail, Paris will be destroyed by the creatures that threaten it when the swarm hatches and decimates the city.
