What to read after A Cappella Boy?

Sameer, a young boy of ten years, is not like all other normal children. He will never be able to read and write. His speech is slurred and incoherent. His mother has given up trying to get Sameer educated. But a young girl of his age, Dipti, enters his life. She discovers this amazing talent in Sameer, his ear for music and ability to produce a cappella music – the exact sounds of musical instruments with his own voice. There is no looking back after that – Sameer turns into a famous musician, a star.
