The author and his 19 year old son, Jack, pulled off their goal of Australia to London by motor vehicle, though the project was nearly derailed entirely at a few points. They begin by ship to Timor Leste (East Timor) to see how that new nation has recovered from years of brutal Indonesian occupation, and then on through Indonesia and southeast Asia to China - which takes up a large part of the story - and then west through Mongolia, the 'Stans, Iran and Turkey.
Most of the book is narrated by Jon Faine, in a manner strongly reminiscent of Michael Palin (with an Australian accent). Jack makes a few comments here and there, as well as reading a couple of long sections from his point-of-view late in the saga.
Jon's reading was quite clear, but the first half of the book seemed rather dull to me. I confess that I was a bit turned off by his interjection of so much politics, such as his French friends who were "in exile" in Asia in despair over Sarkozy's election, etc. Ho Hum. Jon has a sense of humor - his depictions of food, regulations, and such, are sometimes laugh-out-loud funny. However, there are times where his pessimism over poverty, etc. struck me as grim; he also seemed a bit naive for someone from his background. Bottom line: he and I wouldn't likely be pals, but I give him credit for his accomplishment.
Jack ... on the other hand ... I couldn't really get a handle on. I'd thought he was much younger until his actual age was mentioned. On the one hand, he's mentioned as having traveled extensively himself, but on the other, he sometimes seems overwhelmed by the situation. There's a scene in Turkmenistan(?) that's done in the format of a theatrical script (which went on longer than it should've), where Jack's navigation skills are a complete mess. If he were really that inept, they'd likely never have made it as far as Darwin! I fast forwarded through his longer sections as he seemed to mumble to me.
I'd recommend the book as the story of a unique experience, although the parts didn't make a cohesive narrative for me.
