Book excerpt: Funny and fanciful, this is a book about a Coca Box, and an unlikely travel foursome exploring the art and archaeology of Peru. Except that one member of the team likes to collect Precolumbian pottery. If trafficking in archaeological materials is unlawful, it seems to matter little, and in the end it appears her efforts were futile. Everything she bought was fake. Or was it? We may never know. Meantime we bounce over desert tracks along Perus North Coast, through the high canyons of the Central Andes, and across the windswept Altiplano where snow-capped volcanoes pierce the bright blue sky. An enchanting book.
