From back of book: Kit Marley, poet, playwright, and spy in the service of Queen Elizabeth, has been murdered. His true gifts to Her Majesty were his way with words and his ability to craft plays infused with a subtle magic that maintained her rule. He performed this task on behalf of the Prometheus Club, a secret society of nobles engaged in battle against sorcerers determined to destroy England. Assuming the deceased Marley's role is the talented poet and player William Shakespeare, but he is unable to create the magic his queen and country require to hold its enemies at bay.

England's only hope resides in Faerie. Kit Marley, resurrected by enchantment, must now serve Queen Mab. Caught between two worlds and two allegiances, Kit knows that the only way to save both is to assist Will in the art of magic...and to reveal the traitor within the Prometheus Club responsible for his death.
