Born of Night — Sherrilyn Kenyon

In the Ichidian Universe no one was safe people were dragged from their homes and killed in the streets. Victims of a ruthless tyrant who was bent on being the sole ruler. Those who opposed him formed an alliance called The League, which fell under the leadership of the Quorum.

The Quorum realized that the best way to keep trouble from starting was to cut it off at its knees. So a separate group of soldiers was needed, The League Assassins. Highly trained and highly valued, they are the backbone of the government. But not even the League is immune to corruption...

Command Assassin Nykyrian Quikiades was born and trained to slaughter. Refusing to be a pawn, he turned his back on the League and has been hunted by them ever since. Though many have tried, none can kill him. Now his assignment is to protect Kiara Zamir, a woman whose father's political alliance has made her a target. She wants nothing to do with politics, yet she is forced to submit to protection or die.

And as her world becomes even deadlier, Kiara must entrust her life to the same kind of beast who once killed her mother and left her for dead. Old enemies and new threaten them both and the only way they can survive is to overcome their suspicions and learn to trust in the very ones who threaten them most- each other.
