Sometimes a river.

In Rivers of America (Abrams, $40), Tim Palmer urges the reader, through images and words, to recognize the significance and beauty of the rivers and streams of America, and to connect with what he calls "a life-force of great importance." As Palmer explains what rivers have meant to him in his life, he also explores why they're important to America--both to our threatened ecosystems and to society as a whole. Palmer's vibrant photographs capture the energy and spirit of the rivers that bring them to life. Rivers of America will captivate fans of photography and nature, and remind the reader of the natural beauty that still exists in the U.S.
