As Greenwald reminds us in "The Size of The World": The purpose of travel is to eventually return to the place that you started at, and see it through fresh eyes. With this goal in mind the author sets out on an epic circumnavigation of the world via land travel only. This he accomplishes depite often having to take the long way round. His experiences, as with any travel book of this nature, make for escapist and highly enjoyable reading. I frequently found myself wondering if I could cope with some of the situations he's presented with throughout his adventure. And a world tour, however you accomplish it, is always going to be a serious adventure. The book begins with the lengthy preparations for his journey, which include finding a suitable travelling companion, in the end someone so self consumed with finding her self that I was eventually glad the author continued the journey alone. The book becomes somewhat focused on the author's experiences, past and present, in Nepal, a region that Greenwald, and his travelling companion, are strongly drawn to. I felt that other equally challenging regions of the world were too briefly dealt with or ignored entirely. But then there is only so much that you can relay in a single book. All in all however an excellently crafted travelogue. Try Tim Cahill for stories of adventure travel in equally remote areas coupled with a good dose of humour.
