To Kill a Shadow by Katherine Quinn

Jude Maddox knows nothing of love or even light. He knows only his grim duty as the Hand of Death, to lead the Knights of the Eternal Star into a land filled with nightmares and certain demise. It’s only when he sees her―a young woman with wild, amber eyes who’s as fierce, defiant, and swift as the shadow beasts themselves―that he feels the warmth of life in his blood…

The other Knights may fear their lethal commander, with his hard, merciless demeanor. Outcast Kiara Frey sees only a leader, a man who knows how to survive. Someone like her. But wanting him is as treacherous as the shadows themselves… and just as seductive.

With a kingdom on the verge of collapse, the Knights must now venture into the darkest heart of the land and uncover the secrets of the misted shadows, where evil will prey upon their minds and feast on their flesh.

It will betray their senses.
It will surpass their nightmares.
Most of them will die.

But they have no other choice. Because the only way to fight the darkness…is to become it.
