Fangs and Family by Olena Nikitin

The only person who can save my brother is the vampire who hates me.

My brother disappeared, his friends were slaughtered, and the man searching for him used mind control to force me to help find him.
Desperate to save Pawel and retrieve the ancient artefact he stole before his enemy destroyed my life, I turned to my nemesis – Adam, hoping the price for his help wouldn’t leave me broken beyond repair.
Because we had a past, and it wasn’t a good one.
I hurt and humiliated him; this would be his chance for revenge.
But what else was I supposed to do? Let him call me his Obsidian when he gently stroked my hair? I’m just Nina, a human with no power, and I had to protect myself.
The irony is I would give anything to hear those words again, but now that my life depends on him, I don’t know if Adam would fight for me again.
