A parent would reach for this book when their teenager seems to be losing themselves while trying to keep everyone else happy. It is a vital read for the 'helper' child who prioritizes family harmony over their own needs. The story follows Scarlet, an introverted girl who finds herself caught in a complex web of loyalty and longing when her pregnant sister returns home with a husband Scarlet finds herself drawn to. Through Scarlet's journey, the book explores the messy reality of family boundaries and the courage required to say 'no.' While it touches on the intense crush Scarlet develops for her brother-in-law, the core focus remains on her developing self-confidence and learning to stop being a background character in her own life. It is a sophisticated, realistic look at emotional maturity for older teens.
