'Tis not often my wife and I are split on a book, but it happened in this case.
First off: The book - about a well-educated work-shy guy who decides an indeterminate time off on a desert island would be quite fun. It gives a realistic picture of what living on a very small island in the middle of nowhere is really like. To give the author (and his wife) credit, they did integrate well into the island environment, meeting a lot of the locals and managing to survive. And perhaps did some good. There are also some good stories, some of which are very funny - in particular an episode with an ill-advised sail to a nearby island and a shark.
I score it low because of the writing style - which didn't bother my wife so much, which explains the split. The first part of the book, for the first few chapters anyway, was characterised by very long sentences, with a lot of commas, and asides, which I think was meant to convey a relaxed writing style, which was supposed to reflect the authors laidback attitude, which it didn't, well not really, at least in my opinion, which is important as I am the reader. See what I mean? After 20 pages of that I was crawling up the wall; I never quite forgave the book.
After a while it settles down. But it still feels like a first-time author's book - to me the good story was held back by the uneven style. If writing style doesn't bother you too much, you will probably enjoy it more than I!
