The Vampire’s Ultimatum by Martha Woods

On the run from the police and running out of allies, Amy has been backed into the corner.
Given an ultimatum that no one ever wants to receive:
“Your life, or your friend’s lives, you choose.”
With precious little time and even less patience, she’s going to have to use all the resources that she has to save her friends and keep her head on her shoulders, but with stakes running high and tempers running even higher, who’s to say how this will all turn out?
One way or another, everything ends tonight.
The only question is… for who?
