The Twilight Lord — Bertrice Small

Lara, Domina of Terah, has mysteriously disappeared while visiting the New Outlands. The Dominus is frantic to find his beloved wife, but when no trace of her can be discovered, Magnus Hauk turns to two strong allies--Prince Kaliq of the Shadows and his mother-in-law, Ilona, the most powerful of the faerie queens. Who has stolen Lara? And why?

In the Dark Lands, Kol, the Twilight Lord, revels in his victory. The faerie woman Lara is now his possession, and her powers will soon help him to conquer first Hetar and then Terah. But the Emperor of Hetar is hatching schemes of his own--having learned of Lara's disappearance he believes Terah is now vulnerable, and plans to go to war against Magnus Hauk.
