Please help me find a book I read 30+ years ago. The plot is about a young, very poor boy in India (I believe) who gathers rare Orchids to sell to a rich white (I believe) woman. With the money he earns, he is able to buy books. The books are rare and precious treasures to him. Every time he finds a rare orchid she buys it and he hides his money under his sleeping mat until he has enough to buy a book. I will try to remember more if possible. Thank you, this is a book that has stayed in my memory and I wish to find and read it again.
