Carol Wall, a white woman living in a lily-white neighborhood in Middle America, was at a crossroads in her life. Her children were grown; she had success; had overcome illness; her beloved parents were getting older. One day she notices a dark-skinned African man tending her neighbor's yard. His name is Giles Owita. He bags groceries at the supermarket. He comes from Kenya. And he's very good at gardening.

Before long Giles is transforming not only Carol's yard, but her life. Though they are seemingly quite different, a caring bond grows between them. But they both hold long-buried secrets that, when revealed, will cement their friendship forever.
