In 1982, Eric Hansen - who must have then been no more than 27 or 28 (?) - walked (that's right.... walked) across and through the tropical rainforests of Borneo... sometimes with native guides, but sometimes by himself. He spent months in the rainforest. Then, when he was 50 miles from from the east cost of Kalimantan, he suddenly (and impulsively) turned around and trekked back to Sarawak. This book describes this fascinating journey. The author is an intelligent and unpretentious man. Especiallly interesting are his descriptions of the forest itself, which is vivid, and his marvelous tales about the Penan and about the Kenyah in Apo Kayan. A fine and worthwhile book.
