I know it should be 4 stars but...
I really don't know how to review this book, it's so special, and different and, in it's own way, brilliant.
The way it is structured gives us the contrast between what's changeable (people living in the house, reforms made, periods of History, etc) and what's not (nature, who's also ever changeable but humans have a too short lifetime to witness it). That's why you need to be extremely attentive when reading it, because there are always "correspondences", things repeated, or parallel to what has been said before, etc.
Also, the narrative is also quite different. Normally it is not linear, it uses a lot of flash-backs, and it is written as if it were the line of thought of the character.
It's an excellent book, also quite depressing in my opinion (in a good way), but I really recommend it.
