Trying to find a book about a south asian girl who stops talking (we saw it in a store but they dont sell it anymore, and dont remember).. ,…,

Hello,

I am looking for a book about a little girl who stops talking. It’s a fiction of about 250 pages or so and the author’s surname is either A or B. It might be based in India, Sri Lanka or a south asian country. I know its a long shot.

Thank you
