G-baby and her younger sister, Peaches, are still getting used to their "blended-up" family. They live with Mama and Frank out in the suburbs, and they haven't seen their real daddy much since he married Millicent. G-baby misses her best friend back in Atlanta, and is crushed that her glamorous new stepsister, Tangie, wants nothing to do with her.
G-baby is so preoccupied with earning Tangie's approval that she isn't there for her own little sister when she needs her most. Peaches gets sick-really sick. Suddenly, Mama and Daddy are arguing like they did before the divorce, and even the doctors at the hospital don't know how to help Peaches get better.
It's up to G-baby to put things right. She knows Peaches can be strong again if she can only see that their family's love for her really is like sky.
