Callum Harker, PI, never believed in the supernatural. When a small harbor town on the coast of Otravire falls under siege from an unknown entity in the night, he is certain that the culprit is human, and he intends to bring them to justice himself if the nobility won't protect their counties.  Callum's investigation leads him out of the Capital City and into the heart of Umbra Harbor, where the townsfolk are wary of strangers, almost every window is adorned with ropes of garlic, and the citizens are being tormented and killed under cover of darkness. Strange dreams, bouts of fainting, mysterious bite marks, and victims completely drained of their blood are all tell-tale signs of where the Bloodsucker has struck.  With the help of an eccentric local doctor, and the mysteriously charming Count of Umbra Harbor, Callum must lure the culprit out of the shadows, or risk becoming the next victim of the dreaded Bloodsucker.
