The Good Sister

Rose and Fern Castle are twin sisters with an unshakeable bond forged by their difficult childhood.

When Fern decides to help Rose, who cannot have children, by becoming pregnant herself, long-buried family secrets begin to surface. Through alternating perspectives and diary entries, the story reveals the complex dynamics between the sisters and their shared past. The sisters' childhood memories don't align, forcing both women to question everything they believed about their family history and their roles in each other's lives. The narrative builds tension as the truth threatens to unravel their relationship. The Good Sister explores the nature of family bonds, memory, and the lengths people go to protect those they love. The book raises questions about perception, truth, and whether good intentions can justify questionable choices.
