When Sir Walter Conrad discovers a new energy source, one that could topple nations and revolutionize society, the race to dominate its ownership begins. But the excavation and use of this energy source will have dire consequences for both humans and fey. For an ancient enemy stirs, awakened by Sir Walter's discovery.

Outcast half-fey Effie of Glen Coe is the Empire's only hope at averting the oncoming disaster. Effie finds herself embroiled in the conflict, investigating the eldritch evil spreading throughout the Highlands. As she struggles against the greed of mighty lords and to escape the clutches of the queen's minions, her comfortable world is shattered.
