Dance of the Will'o'wisp

When Bree Tellers parents are killed in a freak accident involving an unknown species, she is thrust into the face of a new world. A world that she never even knew existed, and never hoped would. The Fae are warriors from long ago, placed on earth to fight the dark forces. But some dark forces are disguised as light, and Bree begins to question the truth about light and dark. Is there both, or only one, in the end?
