City of Time and Magic sees Xanthe face her greatest challenges yet. She must choose from three treasures that sing to her; a beautiful writing slope, a mourning brooch of heartbreaking detail, and a gorgeous gem-set hat pin. All call her, but the wrong one could take her on a mission other than that which she must address first, and the stakes could not be higher. While her earlier mission to Regency England had been a success, the journey home resulted in Liam being taken from her, spirited away to another time and place. Xanthe must follow the treasure that will take her to him if he is not to be lost forever. Xanthe is certain that Mistress Flyte has Liam and determined to find them both. But when she discovers Lydia Flyte has been tracking the actions of the Visionary Society, a group of ruthless and unscrupulous Spinners who have been selling their talents to a club of wealthy clients, Xanthe realizes her work as a Spinner must come before her personal wishes. The Visionary Society is highly dangerous and directly opposed to the creed of the Spinners. Their actions could have disastrous consequences as they alter the authentic order of things and change the future. Xanthe knows she must take on the Society. It will require the skills of all her friends, old and new, to attempt such a thing, and not all of them will survive the confrontation that follows.
