He's temptation incarnate. She's a vow away from giving it all up. From Sierra Simone, USA Today and Wall Street Journal bestselling author of Priest, comes a sinfully seductive forbidden romance where faith, lust, and redemption collide. Sean Bell is wealthy, wild, and unapologetically wicked, a man who's never believed in forgiveness or forever. But when Zenny Iverson reenters his life-his best friend's little sister and a novice nun with one month left to choose her path-everything changes. She wants to know what desire feels like before she takes her final vows. And she wants Sean to be the one to teach her. What starts as a dangerous game becomes something neither of them expected: raw, soul-shaking intimacy that forces them to question everything. Unholy in the best way, intensely emotional, and spiritually erotic, Sinner is a taboo romance that cuts deep and burns hot.
