Melusine believes keeping her faerie nature a secret from her human husband is a sensible decision, though her past pairings have been ill-fated. Handsome and charming, Raymond could be the one to break the curse and give Melusine strong children, who might revitalize the faerie people. Their love is true, and Raymond trusts Melusine deeply, even with her one requirement: that she have one day each week to herself. But when court gossip fractures their trust, Melusine's carefully forged currents of magic shatter.

When their children, unschooled in their powers, become overwhelmed by the strangeness of their lives, Melusine's plan spins out of control, leading to betrayal, death, and destruction. Geoffrey, their heir—unnerved by events he doesn't understand—must come to terms with his true nature if he is to save his family. On a frightening new path, he is challenged by a giant, his relentless faerie grandmother, and a host of beings who know his every fear.
