Rolf Margenau has written six novels and published two photography books. The novels feature a main character named Wylie Cypher, first seen as a twenty-year-old college dropout who comes of age during the Korean War. At forty, Wylie is a successful but burned out lawyer with a failing marriage. He tries to find lost youth on a trek with his daughter through the high Andes. Instead, he finds mayhem, murder, a devastating civil war in Peru, and loses a toe.

Retired, in his mid-sixties, Wylie does battle with BIG AG as a Master Gardener. He befriends a group of eco-terrorists who help save the Monarch butterfly. Then, in a novel called National Parks, an aged Wylie lives in a dystopian future where Congress attempts to sell off our national parks.
