Very Big Sister:
Being a big sister to a new baby brings big responsibilities.
Sona Sharma's house is full of people who joke often and argue sometimes. Relatives come unannounced, the phone rings frequently and friends drop in all the time. Then one day Amma tells Sona she is going to have a baby. Is that good? Sona isn't sure - she has always enjoyed being an only child - and straight away she has a word with her best friend, Elephant. When Sona learns that there will be a baby naming ceremony, she is determined to find the perfect name for her new brother or sister. Because although she realizes that her life is about to change, and while she's having some difficulty in coming to terms with having to share everything with the new baby - including Amma and Appa, her grandparents and her home - Sona Sharma wants to be the very best big sister she can be.
 
Looking After Planet Earth:
Sona Sharma combats climate change.
When Sona learns about the climate crisis at school and is very worried that no one is doing enough to combat it, she takes up the challenge herself. But Appa isn't amused when Sona throws out her baby sister's nappies and Thatha isn't happy when she tells him to get rid of his colour-coded plastic files. When Sona learns that many of the kolams - the traditional art that people draw in front of their homes to celebrate the winter months and the festival season - are not organic, she sets out to make some big changes by getting everyone involved.
