England flourishes under the hand of its Virgin Queen: Elizabeth, Gloriana, last and most powerful of the Tudor monarchs. But a great light casts a great shadow. In hidden catacombs beneath London, a second Queen holds court: Invidiana, ruler of faerie England, and a dark mirror to the glory above. In the thirty years since Elizabeth ascended her throne, fae and mortal politics have become inextricably entwined, in secret alliances and ruthless betrayals whose existence is suspected only by a few. And two courtiers, struggling for the favour of very different royal patrons, are about to uncover the secrets that lie behind their thrones. What they find has the potential to fracture both worlds. This is a breathtaking novel of intrigue and betrayal set in Elizabethan England.
