The Edge — Belladonna Bordeaux

Their love is defined by the undiluted truth. Royal Vampire, Princess Rhine Cordaire will forever suffer from the effects of the dreaded Blood Poison, an infection that leaves her unsure, and at times lost to logic. It is an aspect of her life she'd rather not consider, but what else is there for the pampered princess? Nothing. That is, until one dark night, she meets a man who isn't afraid of the infection. He isn't afraid of anything.

Hailing from the Royal House of Dragul, Prince Nikolai Vladstock understands Rhine better than she does herself. His family is attached to her family by a common thread; one forged thousands of years ago. Though his family's secret delves deeper, more abhorrently so, into the history of the wives of Adam than hers, he must follow the one thing that has guided him to the truth; his instincts.

How will he ever get her to accept the fact that she is married to a creature? One born from an atrocity that had no name because she repulsed the first man.
