I did finish reading the Time Traveler's Wife. I have read it before and didn't talk much about it at the time. I figure not everyone share's my fascination with time travel - yall know I can read and/or watch almost anything with time travel as a topic. (Not Dr. Who - too British)
The book is full of the discussion of the paradox that is time travel (how many of your eyes just glazed over?) but I loved it. How much can you change? Can you change anything? Would you change anything? Our main character, the Time Traveler, said "it already happened" whenever asked to change anything. It's hard for me to get my mind around even now.
Overall, I would recommend it. Bad language and some se*ual situations so be forewarned.
