It is difficult to elect a favorite book, I think this one makes the top of the list though (together with little women for obviously completely different reasons). I love it not only because of the excellent style, of the period which is inspiring to say the least, but foremost because of its actuality and timelessness, as well as its irony of course, that never turns into sarcasm although more then once the bitterness can be felt.
Like "Little Women", and that is the sole parallel I want to make, this book has been more than once a pleasure, a rest, or even a refuge, and always a reference point in my reading history.
If you have not tried it yet, do. And tell me what you think, I am amazed at every new facet I discover when discussing it with other readers.
