A young ginkgo tree planted outside an apartment building grows each year, getting to observe the lives of the residents of each floor as it gets taller. The different floors it passes through represent different stages of life and the tree experiences happy times and sometimes sad, painful, and lonely times as well. Readers will enjoy the muted yet detailed illustrations along with the simple, philosophical text.
