From Russia With Blood by Vivian Murdoch

I am a predator – a cold-blooded killer. Nothing and no one gets in my way.
As an up-and-coming, prominent member of my house, it’s my duty to prove myself.
The last thing I need is to catch feelings for a human. They’re so fragile, so easily crushed.
But one taste is not enough. It will never be enough.
