Wages of Sin (Cin Craven #1)

Dulcinea Craven descends from a long line of witches, and she has just inherited wild, untrained magical powers that she has no idea how to control. Now a ruthless vampire and an age-old demon are determined to enslave Cin and steal her power for their own. Her only hope is The Righteous, a band of warrior vampires who slay the rogue undead.

Among them is Michael, a fierce swordsman who inflames Cin's most primal hungers. Showing her a sensual pleasure beyond anything in the mortal realm, she must choose between the human existence she has always known, and immortality as a vampire—a new life filled with forbidden urges, dark yearning, and unearthly passions.
