Night's End

Eons ago, vampires tried to turn the dark Fae in order to harness their magic, only to create a demonic enemy more powerful than they could have imagined. Now, in a final push, Myst returns with a vengeance to bring the Golden Wood forever under the rule of the Indigo Court.
Newly crowned Fae Queens Cicely and Rhiannon have embraced their destinies and claimed their thrones. But Myst is rising once more, and now, at the helm of her armies, she begins her final assault on the Golden Wood. As Fae, vampires, and magic-born alike fall under the tide of blood, Cicely and her friends must discover a way to destroy the spidery queen before they—and their people—face total annihilation.
