As always, I will provide no spoilers... but I will share my two favourite quotes from the book. These quotes were the only ones that I found vaguely noteworthy.
"Many human beings say that they enjoy the winter, but what they really enjoy is feeling proof against it. For them there is no winter food problem. They have fires and warm clothes. The winter cannot hurt them and therefore increases their sense of cleverness and security."
"You're all alone, sharp and clear, like a dead branch against the sky."
If the book would have contained more quotes like these two, I would have been hooked. The book really read to me like two separate novels. There was not a lot of plot until the 3rd part (there are four parts) of the novel, where the intrigue started. At this time, the concept of an alternate rabbit society made the story much more interesting.
The author also used quotes in different languages, with no translations. While the quotes loosely described the chapters they represented in the book, they did nothing to foreshadow or add to the story in the slightest.
What I did find very interesting was the portrayal of different areas of society... country folk, Russians, women, etc. I don't know exactly what Adams was trying to say, with his stereotypical portrayals, but it did add a lot of intrigue.
Overall, I wouldn't recommend this book... but it's probably better than a lot of the other rubbish considered literature these days :).
