Bloodsong (The Bloodsong Series Book 1) by Serra Rose

Quinn thought launching this new step in her singing career would be the only thing on her mind. But fate, it seems, has other plans. Because the sexy and mysterious stranger who comes to watch her sing immediately grabs her eye-and stirs all her wildest fantasies.
 
Except Matteo has deep secrets, and when Quinn catches him mid-feed, a whole new world of vampires is opened up to her. And she's his new obsession.
 
In all his centuries, Matteo has never seen a masterpiece like Quinn. The second he hears her voice, he knows she's meant to be his. His to claim. His forever. Just his.
 
Torn between normalcy and this dark new reality, she's unsure how long she can resist her desire and the danger it brings-now that his hunger has drawn deadly attention.
 
He wants to taste her, she wants the thrill of his embrace. In the end, their love could consume them...or be the one thing that sets them free.
