This true-life adventure-travel story follows John Harrison and his wife Heather deep into an unexplored region of the Amazon rainforests in the Guiana Highlands that border Brazil. With just a canoe and a shotgun, the newlyweds followed the most remote tributary of the Amazon River without any means of contacting civilization. Harrison tells their story as, unaided and off the map, they encounter jaguars and poisonous frogs, are threatened by malaria, and almost lose their way entirely. While experiencing travel at its most raw, they struggle to keep their deteriorating sanity and relationship intact in one of the most hostile and unforgiving places in the world. Far more harrowing than reality shows like Survivor and Amazing Race, this is armchair adventure at its most honest and compelling.
