It is not easy being Margaret Leng Tan. Her obsessive-compulsive disorder (OCD) is her constant companion and counting controls her life. Imagine her joy and relief when she began her first piano lessons and discovered where counting truly belonged... in music!

This is the story of how Margaret made friends with her OCD. It is also about how she became the world's first toy piano virtuoso.

This book is the first title in the Becoming Extraordinary series featuring people who overcame challenges to excel in their fields. This inspiring true story is based on the life of Margaret Leng Tan, who is a living role model for children dealing with challenges of their own. The books in this series provide a fitting platform to engage children to discuss hard topics such as mental disorders, about having different abilities and accepting differences.
