A heartwarming story about the relationship between a girl and her grandfather.

When Mayumi was born, her grandfather built her a garden. It had no flowers or vegetables in it. 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. But then one summer, everything changes. Ojiichan has grown too old to care for his home and the garden. He has to move. Can Mayumi find a way to keep the memory of their garden alive? Children will be moved by Mayumi's devotion and ingenuity.
