My thoughts on the book--"Not the End of the World"

Can't say this book is good either...'Tis a bummer. I don't wish to make blanket statements so I shall explain...
----
First, here is the synopsis for the book, which I got from http://www.andy-moore.co.uk/bookclub/viewtopic.php?pid=73

"Everyone knows the story of the Flood, the men God chose to survive, the animals that went in two-by-two. But that about the others that sailed on the Ark, the women and the children? This adventure story asks what it was really like when the heavens opened and the world drowned – and what might have happened in the days that followed.With a frighteningly zealous and single-minded Noah; Japheth and his young wife Zillah concerned for the welfare of the animals; the stowaway boy and baby found by Noah’s daughter Timna; and the animals themselves, continuing to act as animals do, whatever their surroundings, this is an extremely compelling and at times very frightening story, beautifully written as ever by Geraldine McCaughrean."

Now, here are some notes I took after reading the book a while back:

-The author took too much liberty:
~At one point, Shem was beating his wife [in the book] because an animal had come and killed their baby daughter.
~I know that no one is perfect but Noah and Noah's family was mostly portrayed as a bunch of foolish, overzealous, ignorant nincompoops who don't know anything or aren't [except for the main character, Noah's daughter and some others] compassionate at all towards the people left behind during the flooed. They follow Noah blindly.
~Shem's wife was trying to poison him.
~They [including Noah] kidnapped a girl to be Japeth's wife.

-The story made it out as though others had survived the flood even though Noah thought that they were to be the only ones and kept telling everyone on the ark that others would be destroyed. The writer of the book seemed to think that it didn't make sense for Noah's grandchildren to have married each other so there must have been others who survived. In the book, they spoke of how wrong it was to marry family members in the story. [But had God said it was wrong at that point? Besides, Adam and Eve's children had to marry each other to populate the world the first time...]

The storytelling seemd poetic at times but there was too much...wrongness. And don't let the fact that it was awrded the "Whitbread Children's Book Award" make you decide it must be awesome. Maybe it is for the people who are not Christians and just see Noah's ark as a story--nothing to be taken seriously or anything.

I disliked the book immensely.

So those were my thoughts on "Not the End of the World" by Geraldine McCaughean.

(I should have known when I read the cover--"Geraldine McCaughrean Carnegie Medal-Winning author of a Pack of Lies--that something was wrong.)

Have any of you read this book? If so, what are YOUR thoughts?
