Sona Sharma, Very Best Big Sister?

Sona Sharma's house is full of three generations of people who joke often and argue sometimes. Relatives come over unannounced, the phone rings frequently, and friends drop by all the time. Then one day, Amma tells Sona that she is going to have a baby. Is that good? Sona isn't so sure. She doesn't want to share her room or her things with a new baby, not to mention the attention of Amma, Appa, Thatha, and Paatti. And despite Amma's assurance that the sky always has room for new stars, Sona doesn't feel stretchy or big-hearted like the sky. But when she learns there will be a baby-naming ceremony, she's determined to find the best name for her new brother or sister--one as nice as her own, a Hindi word for "gold."
