The Professor's Garden by Ben Maclennan and Elizabeth Andrew

In an overgrown garden, the old professor and his young neighbor collect fruit, tender vegetables, and share thoughts in the shade of the old plumree. Just before he dies, the professor gives his young friend a special gift to help her remember their time together, and to understand the natural cycles of life and death and renewal.

This book emphasizes the power of memory, and intergenerational relationships.
