Black Hellebore by Grace Draven

Brishen and Ildiko return in this latest addition to the world of the Wraith Kings.

To protect his people and save his kingdom from destruction, Brishen Khaskem made an unthinkable sacrifice, stripping all but the youngest Kai of their magic in order to transform himself and four others into powerful Wraith Kings who would battle the ancient malice known as the galla.
But victory comes at a high price. The loss of their sorcerous heritage is a bitter consequence for the Kai. When an unexpected enemy threatens the lives of his beloved wife Ildiko and his adopted daughter, the queen regnant, Brishen may pay the highest price of all. What will be the ultimate cost of reviving a dead legacy and regaining a lost hope?

A tale of trust and deception.
