In Trouble Again A journey between the Orinoco and the Amazon.......Redmond O'Hanlon
If you like reading adventure travel you might be familiar with O'Hanlon.........but then again maybe not. His books read like a novel and I consider his prose without peer. A superb writer. I read anything by him........rather dry sense of humor and quite the traveller doing some very gritty trips.
"Into the heart of Borneo" is another fabulous read. Check him out......you will likely not be disappointed.
