While in France to petition King Louis XIV to aid the exiled King Charles, Sir John Marstone stumbles upon a street urchin in a fight for his life. After saving the boy, he quickly realizes that he is a she--and no mere homeless waif.
Indeed, she is noblewoman Catherine de la Fer, and her family is offering a reward for her safe return, a reward that would surely help in his cause. But otherworldly acts and creatures haunt them on their way to her home, and love threatens to sway him from his duty to his king.
The world of the de la Fer family continues to develop in this sequel to Night Fires.
