Claiming Marcus (Lords of Discord Book 1) by Jocelynn Drake

Ethan wants revenge. Vampires slaughtered his family. When a job opening comes up for suspected vampire Marcus Varik, Ethan is sure fate is finally smiling on him. Except his new boss is nothing like he expected. Shy, awkward, incredibly protective, and so perfectly sexy. Ethan was definitely wrong about Marcus and the Variks, but is it too late to stop the deadly events he has set into motion? Will he lose the love shining in Marcus’s eyes? Claiming Marcus is the first book in an MM paranormal romance series that has vampires, betrayal, annoying brothers, a two-hundred-year-old virgin, music, heartbreak, hope, sexy times, and a raven named Ozzie.
