"Light and fast-moving. . . . Among the botanical and anthropological observations, one catches glimpses of Sacks's inner life: his preoccupation with dualities, his nearly Victorian sense of modesty, his fascination with the world around him." --The New Yorker

Since childhood, Oliver Sacks was fascinated by ferns: an ancient class of plants able to survive and adapt in many climates. Along with a delightful group of fellow fern aficionados--mathematicians, poets, artists, and assorted botanists and birders--he embarked on an exploration of Southern Mexico, a region that is also rich in human history and culture. Combining Sacks's enthusiasm for natural history and the richness of humanity with his sharp and observant eye for detail, Oaxaca Journal is a rare treat.
