Hugh is a great scientist; I wouldn't necessarily say he's a good writer. There are several Reasons to Believe books that he has written, and they each focus on a particular aspect of the Reasons to Believe creation model (short version: Old Earth / Universe created by God specifically for human occupation at this point in history).
By the end of the book, I was getting a little tired of the repetition. Every single chapter started out with some story from his past, and that was the only personal tie-in. Then it would go on to say something about "there's no possible way we can list everything about our model here, but here are some highlights." Some of the middle chapters got a bit long and too detailed, but the overall premise of the book was very interesting.
Criticisms aside, it was a very good overview of how scientific models can and should be tested. Of course, Hugh's (and RTB's) model seemed to pass all the tests and answer most of the questions (I guess that was the point). At some times it seemed that some of the "in order for a theory to pass this test it must explain...this thing in the exact same way that my theory perfectly does" examples were a bit contrived. But some of the last chapters were talking about different predictions that each creation model makes, and it's really interesting to see how many had come true or negated parts of the various theories between 2006 (when an initial set of predictions was made) and 2009 (when the book was written). It's also been interesting to see how some of the predictions made in this now-5-year-old book pan out.
It's a little depressing that part of the theory talks about how unique Earth is to supporting not just human life, but advanced civilization of any kind. As a sci-fi fan, and die-hard Trekkie, it's hard to read a theory that states just how unlikely it is that we'll actually encounter other life "out there." But the numbers of factors pointing to Earth's unique support for our life does just seem to keep growing and growing.
It's certainly a "meaty" read in the RTB collection. If you're feeling stumped on your way through it, I recommend just reading the first couple and the last couple of chapters. They really make the good, strong points of the argument, and most of the inner-chapters are just deeper explanations.
