When strangers invaded the city and warplanes roared overhead, the tree watched the girl peek out of the curtained window of the annex. It watched as she and her family were taken away—and when her father returned after the war, alone. The tree died the summer Anne Frank would have turned eighty-one, but its seeds and saplings have been planted around the world as a symbol of peace.
