The Harker Trilogy

They killed my sister and infected me. Now I have to pick up the pieces before I die.  I've spent the last five months trying to find the bastard who took my sister's life and ruined mine.  Being brought up in a family that hunted the supernatural should have helped, but even with a slim chance that I can save us all, there's still the bigger chance I'll die trying.  Unfortunately, there's one important thing my family didn't tell me: When you fight against immortal vampires, you're the one who's running out of time.
