It may not shatter your world, but you'll get a well-written story out of it. The first part of the three is really the best, and it's the one that won the Hugo, but there are quite a few memorable scenes beyond that. I just think it's a really solid journey book, with beautiful writing and some interesting twists and turns. I'll be curious to hear what you thought of the ending.
P.S. I just finished this:
One of the most well-crafted and all-around best books I have ever read. Ever. I devoured it and loved every second of it. I can easily see why it won the Man Booker Prize in 1989. Stark and exacting prose, a dreamlike structure, and a tragedy without catharsis. Absolutely memorable, sad, and beautiful in its poignancy and narrative style.
I'll likely write a full review at some point Thursday afternoon.
