Ojiichan's Gift

From the publisher: When Mayumi was born, her grandfather created a garden for her. It was unlike any other garden she knew. It had no flowers or vegetables. Instead, Ojiichan made it out of stones: ?big ones, little ones and ones in-between.? Every summer, Mayumi visits her grandfather in Japan, and they tend the garden together. Raking the gravel is her favorite part. Afterward, the two of them sit on a bench and enjoy the results of their efforts in happy silence. But then one summer, everything changes. Ojiichan has grown too old to care for his home and the garden. He has to move. Will Mayumi find a way to keep the memory of the garden alive for both of them?
