How I Remarried that Monster

Dianna Brienne frees the abused slave of her estate, Guiscard Lodbrog, only for him to return years later as a vengeful king who repays her compassion with a cruel, humiliating marriage that ends in her tragic death. But fate grants a second chance. Thrown back in time to her twelfth birthday, Dianna must now protect the very boy destined to become her monster before his hatred toward his masters grows deadly. In this life, Dianna won’t be his victim. She will face her future tormentor head-on to rewrite their bloody ending and find a better future together.
