Fourteen-year-old Emily Adams has special powers she doesn't want, a spiteful aunt she can't escape, and a primeval legacy she knows nothing about. But when an otherworldly being materializes, Emily discovers the true purpose of her magical blood and of the danger that threatens to annihilate her world.
Dormant for over a thousand years, an ancient evil has arisen. This time, it will destroy anyone - or anything - that stands in its way.
