About the Book: 

Join the Unknown Adventurer again on this thrilling adventure into the Amazon, which begins with a map discovered in the Royal Geographical Society showing a river that has been mysteriously rubbed out. It leads the Unknown Adventurer and his companion Bibi into a search for this 'last river' that will change their understanding of nature forever. 

This book is a thrilling tale of a voyage into the Amazon rainforest that looks exactly like a real scrap book inside, with smudged pages, handwritten-looking text and even die-cut piranha bite marks from a previous scrape.

The gripping story features encounters with caiman and anacondas, incredible flora and fauna, survival tips and much, much more. The first title in a new series of spin-off adventures from The Lost Book of Adventure.
