Earth has declared war on Eamhain.

Raised by the peaceful Fenodyree as one of their own after her parents' deaths, Lucile Taylor is trying to navigate a life torn apart by invasion. Commander Jacob Reid is a USUK soldier, raised in the bunkers on Earth and ordered to exterminate the Fens without question. Dragged away from her quiet life by Jacob's unit, Lucile's unique ability to command the magic of Eamhain puts her and those she loves in danger. As Lucile and Jacob grow closer in their shared trauma, she learns that the corruption of Earth runs much deeper than she realised.

Now she must fight to keep the secrets of the Ferrishyn at all costs, or risk the entire future of Eamhain...
