The Lamia Hunt

When the hunt for a blood-sucking serial killer goes wrong, two generations of vampire hunters are forced to use all the resources they have to find him, and to make sure he doesn't kill again, but it's not going to be easy; to catch him, they'll have to face danger, violence, a horde of murdered children, and, most terrifying of all, a plethora of absolutely terrible puns.
It's going to be a bumpy ride.
