Author:
Nathaniel Hawthorne

Nathaniel Hawthorne’s 1850 novel follows Hester Prynne, a woman living in a strict Puritan community who is forced to wear a bright red 'A' on her clothing as a mark of her past mistakes.

The story explores how she maintains her dignity while carrying this permanent, colorful badge of shame.
