Having quite a bit of training in ethology (esp. behaviour in domestic dogs and wolves) I was mesmerized by, in my opinion, the accuracy of the LOST MAN's thoughts in the book. Whether it was about his thoughts ("they said he should think in words and not in pictures") or his behaviour, it really stunned me. It's a masterpiece in the description of the development of an originally well imprinted and socialized human being (till the age of 6). The end of the story was a bit of a shortcut, but never mind, there were plenty of pages to be thoroughly enjoyed before that. The lovestory behind it all was partially just that, behind it. But this book definitely doesn't need anything else.
