It somehow took me 9 months to read this book. I bought it as a used English-language book shop in Bangkok for 29 baht because I wanted some trashy science fiction. And boy did this deliver! It's an easy read. I'd read a chapter and then put it down and forget about for for a few weeks, then find it and read two or three more chapters, then lose interest and do the same again.
Should you read it? Well, I honestly don't even know how to answer that. I doubt many bookstores have it. And most people who are in the market probably have already read the first several dozen of the series. If you stumble into it for really cheap, go for it. But I wouldn't go out of your way or pay full price for it.
