"You must find the four Keys to keep our worlds from burning..."Andie didn't expect to be orphaned, and she doesn't want to leave the only house she ever lived in. No parents, no Nan, no one but Anne, a weird woman who carries on conversations with old books and empty purses.

When Anne drops her off at her new home in a small town in The Middle of Nowhere, Texas, Andie is at a loss. Her new guardian, Celeste, claims to have been a lifelong friend of her nan, and is one eccentric figure among many others who live in the small town, all of whom seem to know something that Andie doesn't...

One evening, when the woods behind Celeste's house spirit her away, Andie discovers a secret so incredible she can scarcely believe it: she's half-Fae, half-Witch, and it's her destiny to find the four Keys that will save the Tuatha De Danann from annihilation.

Worlds collide when two of her new friends from school, the sweet, helpful Teagan and the rude bad boy Hunter, join her on her journey to reach the mysterious place known only as Finias. There; they'll find the first Key: the Sword of Light.

As they flee the wicked Fomorians and do battle with the Witch Freya, Andie and the boys forge new alliances and make some more adversaries. Will Andie and her friends rise to the challenge, or is the magical realm as good as gone already?
