Renault De Rosier stands at the crux of a family built upon evil. The sins of the father bathed upon his family in outpourings of the blood of the innocent. Where his father and brother succumb to the temptation of vampiric power, he alone must find his way to survive his father's rise to power beyond the world of men. Faced with an unending path of blood and bodies in his fathers wake, can he stop his own kin from destroying the world and the people he loves? Cyrille L'hernault is a fool for love, tethered to a man who cannot love him back. A bystander to the rising threat of Renault's father, Lord Tristan De Rosier, he finds himself drawn into the web being woven by his own maker and the Lord De Rosier. Desperate for something more than the loneliness of being abandoned by his maker, he finds himself closer than he ever anticipated with Renault. A tale of humanity, love, betrayal, and the obsession for power, The Origins of Sin faces the age old question, what depths can a person go for the sake of love
