The layers of life and heart intermingle with observations of nature’s rhythms and tides on four continents in Shades of Green, Robert Yehling’s first printed collection of poetry and essays in 15 years. Spanning nearly a quarter century, Shades of Green presents more than 60 poems and essays that capture moments experienced in castles, the Italian Alps, Machu Picchu, the Himalaya mountains, a homeless man’s cardboard hovel, an Apollo astronaut’s house, Hopi mesas, a dying youth’s ping-pong table, the eyes of two lovers, and more.
