She's one of those things that goes bump in the night; if only she knew what kind of thing that was...
When Su met Evgeny, he was a newborn vampire fleeing a mad scientist maker, and she was something not entirely human with no memory of her past.
They're happy spending their days trying to figure out where each of them came from, and how they best fit together in bed, when Evgeny vanishes, stolen by a vampire cabal that wants to use his rare ability to metabolize witch blood to make themselves invincible.
Rescuing her new lover from a secret research facility seems to be an impossible task, but Su might just be an impossible creature, and if she fails, Evgeny's best case scenario is to become a mindless blood filter.
The worst case scenario is unthinkable...
