I just finished this about a week ago... what an awesome book! Really was impressed with how much breadth of story telling the author was able capture. After I finished I gave it to my wife and she loved it too
Currently I'm restarting the Dark Tower series... I read up to book four when I was younger (before 5-7 were released) so now I need to re-read the first 4 and then finish the series.
So far I'm really enjoying the Gunslinger... its probably been at least 10 or 12 years since I read it; so now its almost new to me.
