"Get on your knees," he said, voice low, dangerous. "Or I'll show you what happens when an angel disobeys." She shouldn't want him. But wanting is the least of her sins. Harmony was meant to live a quiet life, but ever since the masked demon started haunting her dreams, everything is shifting. Her body. Her cravings. Her memories. As if something inside her is waking up. He's not just a stranger. He's something else. Something ancient. Something hers. And he's not the only one watching. Two demons have marked her: one feeds on her soul, the other would burn the world to protect it. One sees a prize to corrupt. The other sees exactly what she is... and what she could become. She was never just human. And now, there's no going back. Fallen Angel is a dark, seductive paranormal romance about forbidden desire, slow-burning obsession, and the thin line between salvation and ruin.
