Book excerpt: Last Leaf First Snowflake to Fall takes us on a dreamlike voyage into nature at that secret moment when fall turns into winter. We find ourselves in a kind of paradise, which humans may be part of but which they have not despoiled. A father and son lead us through forests, down rivers, over lakes and ponds. Along the way we experience the primordial beauty of the physical world. This is nature as we all feel in our hearts it must once have been. Through lyrical words and a masterful collage technique, Leo Yerxa has created an exquisite and poetic evocation of this moment.
