A poet and naturalist, Nabhan makes his way by foot along the ancient Franciscan Way from Florence to Assisi, talking to farmers and townsfolk en route. This most unusual travelogue combines natural history, spirituality -- and a lively appreciation of local food and food traditions. It's the local scale of Tuscany and Umbria and the accommodation of wild and domestic that intrigues Nabhan. This edition, the only one available, is a print-on-demand paperback.  (ITL99, $16.00)
