As a Christian I have very strong beliefs about the truth and validity of the Bible. I believe in the historical accuracy of the Bible. If you do not agree, that's okay.
I was very dismayed at the portrayal of the account of Noah's Ark in this book. I often read books that take liberties with history as far as the unwritten parts go, but this book goes even farther and directly contradicts the Bible in at least two very major points.
If you know me personally you know that I am often fuzzy on the details of things that I have read. Not so with this book.
The two areas that the book directly contradicts the Bible are as follows.
A. The protagonists are not Jewish but come to the area where Noah is building the ark only to find that he's doing a pretty terrible job. Luckily the father of the protagonist is a shipbuilder and so he sets everyone straight. Sorry, but as a Christian I believe Noah was inspired by God to build the ark and that he knew how to do it correctly with God's help.
B. (Spoiler) At the end of the book we find that there was a human stowaway on the Ark and also in another ship. I firmly believe that the account in the Bible is true and that there were ONLY 8 humans saved in the flood: Noah and his wife, and his three sons and their wives.
Because of these major discrepancies I cannot recommend this book.
