India Drummond2011

Sentenced to death, Eilidh ran—away from faerie lands, to the streets of Perth, Scotland. Just as she has grown accustomed to exile, local police discover a mutilated body outside the abandoned church where she lives. Recognising the murder as the work of one of her own kind, Eilidh must choose: flee, or learn to tap into the forbidden magic that cost her everything.
