Tamara Mikhееva’s “The Book of Trees” resembles a chronicle of a parallel world—one that is very close, yet remains invisible to us. In many ways, it is much like the familiar reality: there are also plenty of matters and adventures, unexpected discoveries and difficult trials. Only tiny creatures live there—shumses. They share a special bond with trees, and they know everything about the trees. This is an audio performance based on the first story about shumses—“Tree Guardians.”
