Jumia Books Sinner by Sierra Simone

Sinner by Sierra Simone is the second book in the Priest series, centering on Sean Bell, a wealthy, arrogant man known as a ruthless playboy who lives a life of sin and disbelief in God or goodness. His life takes a complicated turn when he meets Zenobia "Zenny" Iverson, his best friend’s much younger sister, who is about to become a nun. Zenny challenges Sean to show her every carnal temptation before she commits to her religious life, leading them into a passionate, forbidden relationship full of lust, emotional conflict, and deep questions about faith and love.

Sean, who dismisses morality and spirituality, finds himself falling for Zenny—not just physically but emotionally—as he wrestles with his cynicism, guilt, and the possibility of redemption. Meanwhile, Zenny is torn between her devotion to God and her powerful feelings for Sean. Their relationship forces both to confront their beliefs, desires, and what sacrifices they are willing to make.

The novel blends sensual, intense romance with themes of faith, temptation, love, and inner turmoil, delivering a story of sinners and saints testing the boundaries between sacred vows and profound human connection.

Sinner can be read as a standalone but is part of the Priest series that explores similar themes of religion, desire, and redemption.
