Bought by the Demon Billionaire

Seraphina Redford thought inheriting a billion-dollar empire would make her powerful. Instead, it makes her a target. Betrayed by family, hunted by demons, and forced into the protection of billionaire Tristan Devraux, she discovers his secret: he was exiled from hell, and her soul can restore his lost power. As enemies close in and a blood moon approaches, Seraphina must decide whether the demon who needs her dead is also the only man willing to die for her.
