Dr. Natalie Lambert is the county coroner in Nick's district. She is the single, beautiful, doctor that has taken upon herself the mission of finding a cure for Nick's vampirism. Everything changed in Nat's life late one night when the victim of a gang pipe bomb was brought into the coroner's office. The intern that brought him in said that it was a real mess when he had brought him in, but when Natalie had opened the body bag to start examining the pieces she found that the handsome man inside had little more than a slight cut on his face. He was nothing like the mangled heap that the intern had described. Thinking this must have been some sort of bad joke with the false information the intern had given on the victim, she was then startled beyond her imagining when the dead man on her table suddenly "came back to life" before her very eyes.

Hardly being able to believe what she was seeing she was told that he was a vampire and the hard truth was born home when he grabbed a nearby unit of blood and drank it down hungrily to aid his regeneration. Even more shocking was the fact that she was not afraid of the man before her but felt drawn to him. To the pain and hurt in his eyes. Since that night she has become the only mortal that shares the truth of his real identity, she has become both a trusted ali and one of his dearest and closest friends. While working side by side on various cases and in their combined efferts for a cure their friendship then began to transform into something much stronger for both of them. They must now fight their own growing feelings for one another, to keep from endangering her life due to a pact between Nick and his sire LaCroix that was made centuries before that would forbid Nick the love of any mortal woman. Can Nat find the cure that will cure him and let them finally be free for their love to be realized? The answers await somewhere in the endless knights...
