A headless horseman, a vampire queen, a Celtic werewolf, and a resurrected demigod...

Sean O’Farrell is a monster hunter in full swing now. He’s basically gotten the hang of it.

Wrong.

Life is about to kick Sean in between the legs and spit on his face.

Turns out Celtic vampires have a bloodlust for revenge. And Celtic werewolves are unstoppable forces of nature.

But Sean is also in for a dose of hard truth. The mystery surrounding his dad’s disappearance and death will unfold at the worst time possible. And to get that truth, Sean and his friends are going to have to slash and shoot their way into the dark heart of Celtic vampire territory, and come face to face with a few Earthside Celtic deities.
