Although I enjoyed this book I don't think that it is as good as the previous two in the series. This is mainly because the other books have the believability factor, this book keep on mentioning devastating weather systems and tsunamis, and then largely ignoring them. The story revolving around a religious cult had that air of authenticity about it though.
Unfortunately this was the final book in the series until another one gets written. That is rather disappointing as I have grown to like the characters and the style of writing, still it will give me something to look forward to.
