Viruses, bacteria, fungi, wolves, millennial sequoias, and forests of firs and birches proliferate and spread throughout a work that, following the networks connecting simple and complex organisms, traverses underground stems, school memories, feats of environmental activism, and a natural environment in delicate balance where the language of empire imposes categories and operates through domination and resource extraction. A book that could be read as a natural sciences manual, a botanical encyclopedia, or also, an essay on forest ecology.
