BLOOD HUNGER (Deathless Night Series #1)

Don't miss the exciting introduction into this new world! A world where vampires and werewolves work together to fight a growing evil, where witches have the powers to control them, and where fate plays cupid at the least opportune times.

Emma Moss still has nightmares about the horrors she and her sister saw that summer night. Her sister has not been seen or heard from since, but Emma refuses to believe that she’s truly gone, and continues to search for her. However, she’s running out of resources, and running out of ideas. So when a stranger calls out of nowhere claiming to have information for her, she doesn’t hesitate to go meet him.
     
Nikulas Kreek is a six hundred year old vampire, and he knows a secret about the Moss girls. A secret he soon realizes that even Emma herself is unaware of. A secret that can help them both. But what he didn’t expect, was the blood hunger that would assail him upon meeting her, and the internal fight he would have to resist it.

Bound together by more than they realize, Nik and Emma are on a rescue mission to find their lost siblings. But will Nik be able to resist the blood hunger for Emma, and be able to let her go back to her human life, giving up his own in the process; or will his vampire instincts give him no choice but to make her his?
