Almost four hundred years ago the Fey King Fin Bheara and the human Lord Kirwan pledged to come to each other’s aid if called. When war brews between the Seelie and Unseelie courts, the fate of humans and Fey rests on the shoulders of Mack, the eldest Kirwan descendant. All he has to do is survive long enough to honor the oath his ancestor took.
