No mercy... Three years ago a ruthless Vampire Fem/Dom ripped Doctor Nathan Greer's throat out and left him for dead. Since then he's lived a shadowed existence, trying to pretend he's still human. All it takes is one slip, one moment of letting his guard down, and he can become what he hates most—a ruthless killer—a beast. Now, after three years of self-denial, he's finding it harder and harder to control the Beast. He has no choice but to seek help from his own kind, much as he despises them. His only hope, Guillermo Perez, Kansas City's Master Vampire, and owner of BDSM club Corazon de la Muerte. Guillermo is powerful, sexy, and more self-assured than anyone Nathan has ever known. When he went looking for help, the last thing Nathan ever expected was to fall under the spell of this ancient Vamp himself—and he certainly didn't plan to enjoy himself in another man's arms. It seems Nathan’s still got a thing or two to learn about himself—and about love. Publisher's Note: This title is part of a serial—books which share a universe and are meant to be read in order. This series involves a developing m/m relationship, but the sexual encounters depicted are not solely m/m.

Dr. Nathan Greer has only been a vampire for a little over three years and suddenly a nearly seven foot Viking vampire, Tyrsgard Madds, claims that Nathan is his master. Not only his master, but they are eternally bound and Tyr cannot survive without Nathan. Guillermo Perez, master vampire, club owner and Nathan's lover, hates Tyr. They have a past that neither vampire wants to divulge to Nathan. Guillermo believes that because the bond was created through the "Old Ways" it is unbreakable and he is unwilling to share Nathan with Tyr. Nathan doesn't want or know how to be a master vampire—he can barely control his own Beast. Guillermo worries Tyr will drive a wedge between Nathan and himself. Tyr wants something he hasn't had in nearly 700 years—free will. Publisher's Note: This title is part of a serial—books which share a universe and are meant to be read in order.

Nathan Greer’s unlife is getting turned upside down. His lover, Guillermo Perez, has just bought them a mansion to house Nathan’s vampire servant Tyrsgard Madds,his pregnant ex-fiancé Anna, and Gui’s right-hand, Nadine. And a surprise visit from his mother and two of her PFLAG friends isn’t helping matters. If that’s not bad enough, an old faction of fanatic vampires, the Brotherhood of Truth, is trying to kill Nathan and his unborn child because they believe the child will bring about the destruction of all vampire-kind. Reality is crumbling for Nathan as he begins to dream again, awakens during the daytime hours, and learns there is more to his struggle with his Beastthan he could have ever imagined. On this journey, Nathan and Guillermo discover that TRUTH is stranger than fiction.
