Monarchs, perhaps the best known butterflies of North America, are unusual
for migrating from Mexico to Canada and back. Robert Pyle, a prolific nature
writer, follows their path, meeting people, drinking beer, and observing nature
along the way in Chasing Monarchs. A pleasant trip down the Rockies, avoiding
the major attractions but smelling the flowers. Published by Houghton Mifflin,
£14.99/$24, ISBN 0395828201.
