Peacock's eagerly awaited tale brings us epic personalities, grizzly bears, the trauma of war, and wilderness adventure. A former Green Beret medic in Vietnam, he was mythologised by Edward Abbey as George Washington Hayduke in his environmental classic, The Monkey Wrench Gang.

Described by author David Quammen as "an iconic figure, a secular prophet, in the wildass American West", Peacock has become celebrated for his writing, in particular his book Grizzly Years, and his tireless struggle to help preserve what is wild both in and around us.
