Oliver Sacks, the bestselling author of Awakenings and The Man Who Mistook His Wife for a Hat, is most famous for his studies of the human mind: insightful and beautifully characterised portraits of those experiencing complex neurological conditions. However, he has another scientific passion: the fern.

Since childhood Oliver has been fascinated by the ability of these primitive plants to survive and adapt in many climates.

Oaxaca Journal is the enthralling account of his trip, alongside a group of fellow fern enthusiasts, to the beautiful province of Oaxaca, Mexico. Bringing together Oliver's endless curiosity about natural history and the richness of human culture with his sharp eye for detail, this book is a captivating evocation of a place, its plants, its people, and its myriad wonders.
