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.
