«Immortal Confessions» by Tara Fox Hall

At the turn of the 19th century, former aristocrat turned lowly vampire Devlin Dalcon gets by on his supernatural charms until he meets bride-to-be Annabelle. Smitten by Anna's forthrightness, intellect, and bravery, Devlin risks his life to spirit her away to Fontainebleau, France. There Devlin begins his ascent to power in a desperate bid for wealth and social standing for himself and Anna. Forging alliances with other supernatural leaders, he usurps the vampire Lord of Fontainebleau, amassing many enemies during his brief reign. Within a few years, he and Anna are again forced to flee for their lives to America. Living in hiding, Devlin is determined to amend his ways. But when tragedy strikes, Devlin's dark side, never fully extinguished, emerges rampant, securing him the bloody throne of America even as his malevolence and loneliness consumes him.
