Melusine believes keeping her faerie nature a secret from her human husband is a sensible decision, though past pairings have been ill-fated. Handsome and charming, Raymond could be the one to break the curse and give her strong children to revitalize the faerie people. Their love is true, and Raymond trusts Melusine deeply, even with her one condition for their marriage: that she have Saturdays to herself. But when court gossip fractures that 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, horrific deaths, and destruction. The heir, Geoffrey, unnerved by events he doesn't understand, must come to terms with his true nature and 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. Will he find the courage to face them, and himself?
