In the book Sister Code by Dakai, Diya, and Dumia Valley, the first-time, phenomenal authors have collaborated short stories to share their perspectives and experiences with other girls through readings and exercises about sisterhood, self-love, loyalty, and how their differences make them closer as they grow up. The Valley Girls relate to girls from many backgrounds, which has played a significant factor in their growth to be the well-known sisters that they are. You'll get to read about them as they transition from middle childhood to adolescence, face the most common issues and concerns of tweens and their solutions, and understand why it's super cool to be a Valley Girl.
