In his dreams he is Big-Tooth, one of the "Folk" who compete with the Fire People and Tree People for survival in an inhospitable wilderness. Gradually he comes to realize that his mind has become linked to the psyche of his prehistoric ancestor, and that Big-Tooth's struggles are at the core of his own humanity. A powerful work of imagination, Before Adam will transport you to a world both foreign and familiar.
