In the city of Queen Mab, nothing is quite as it seems. Alizebeth Bequin finds herself caught in a conflict between Inquisitors Gregor Eisenhorn and Gideon Ravenor, former allies now enemies who are playing a shadow game against a mysterious and deadly foe. Coveted by the Archenemy, pursued by the Inquisition, Bequin becomes embroiled in a dark plot of which she knows not her role or purpose. Helped by a disparate group of allies, she must unravel the secrets of her life and past if she is to survive a coming battle in which the line between friends and foes is fatally blurred.
