About The Story
Set in the floating communities of Inle Lake, Myanmar, My Sister’s Big Day follows Maung Maung as he helps prepare for his baby sister Suu Kyi’s first swimming lesson. As he paddles across the lake, readers are introduced to daily life in this remarkable water-based world—boats gliding through lily-filled channels, floating farms, bustling markets, pagodas, monks, buffaloes, and homes built on stilts.
Maung Maung gathers vegetables from his family's floating farm, delivers fresh produce to a monk from the pagoda, and finally purchases a sturdy banana stem for his sister's special milestone. Along the way, children discover how people adapt creatively to life on the water and see how traditions and lifestyles are shaped by the environment in which they live.
At its heart, the story is a warm celebration of sibling love, family responsibility, cultural traditions, and the simple joys of childhood.
