Summer faery princess, half human, Meghan is deserted by the Winter prince she thought loved her, becomes a prisoner of the Winter faery queen, and loses her own fey powers. As war looms between Summer and Winter, Meghan knows that the real danger comes from the Iron fey--ironbound faeries that only she and her absent prince have seen. But no one believes her--and trusting a seeming traitor could be deadly.

Journeying in the lands of the fey, Ethan Chase discovers that his nephew, Keirran, is missing, and may be on the verge of doing something unthinkable in the name of saving his own love. Something that will fracture the human and faery worlds forever, and give rise to the dangerous fey known as the Forgotten. As Ethan's and Keirran's fates entwine and Keirran slips further into darkness, Ethan's next choice may decide the fate of them all.
