Toxic by Eve Langlais [Blood Countess #1]

Humans are for eating and I am not one to play with my food, so I'm baffled as to why one geeky mortal doctor makes me wish our kind could be together without my brand of love being toxic. As if suffering from human emotions isn't problem enough, our world is about to engage in a war where our chances of survival are slim at best. And no one wants to listen.

But, I didn't become the general of the vampire Queen's army by being diplomatic. Everyone will fight in the upcoming battle, or they'll feed my troops and me. Either way, all things living will do their part.

I am, after all, the Blood Countess: toxic lover to humans, vicious bitch to my enemies, and my word is law.
