Locke & Key

Three tales of hunters, vampires, and the colorful lives they lead...
Locke and his partner Key hunt broken vampires—those who did not take well to the changes inflicted upon them, and feast wildly upon the living. They live the life of wanderers, traveling from place to place, putting an end to broken vampires. They rely on each other, partners through and through—until a secret rips them apart.
Preston is a hunter of top vampires, those who have lived for decades, even centuries. It is Preston's duty to keep an eye on these older vampires and ensure they do not break the strict rules by which they live. This duty is easier said than done, when his days are predominantly spent settling the disputes between two vampires with a vehement dislike of each other—but who share a particular fondness Preston.
Trevor has faithfully served top vampire Richard as housekeeper for years, watching from afar as the man he loves notices everyone but the man right in front of him. But then Richard, recovering from a stinging rejection, begins to spend more time with his housekeeper in an effort to get over his heartbreak, and Trevor begins to hope that he might finally get the chance at the vampire he's always wanted.
