I think it is most interesting that off all of the reviews of this book, all are either 5 stars or 1 star...the average is 3.
I choose to give it 3 because I think that is an accurate reflection of it's worth - the average of what people from radically different backgrounds believe is often a good approximation.
This book is interesting, it symbolises the 'scientific' creationist stance on the subject of the flood. This stance is a peculiar one, but it exists nonetheless and this book provides an excellent summary of the literature.
It will obviously be taken in a completely way depending on who is reading it. Those who stand on the Christian side of the debate will likely see a resounding scientific 'proof' for the flood and love this book. Those who are reading it as an effort at researching the creationist standpoint from non-creationist background will hate it.
However, I encourage an attempt at an open mind by all involved. This book is what it claims to be - it is a brief review of the current scientific-creationism literature on the story of the biblical flood. It is not thorough as that would be impossible (as it would with any scientific or religious topic) and it is certainly not balanced.
If you genuinely are seeking a better understanding of this topic, I advise you read this book as one of several - no one will ever be unbalanced on this topic, and a book directed at the non-scientific populous will not contain strong scientific arguments (just read any popular evolution book that comes out of Oxford to see this). This book is an excellent start as it is clearly biased - it is far better to read two books - one from each side - than to read one 'unbiased' one.
In summary, this book is an interesting read, it does what it claims, and it is well written. I cannot give it more stars as it does miss some key points and it does reference since disproved theories. However, I feel that it is a good book for an understanding of this side of the debate and a worthy book for anyone interested to read once.
If you are a creationist you will love it
If you are a non-creationist you will hate it
Really you should see it for what it is - mid-range and a little mediocre
Enjoy
