OK - Stephen King - The Stand - Best Book Ever
I first read it when it very first was published, around 1978 - something like that - I was about 16 and had just got into reading Stephen King, probably after a trip to one of those old Rialto cinemas to see Carrie.
Its not just your basic Good v Evil there is so much more in it than that, you can just lose yourself in the whole thing - in fact I reckon I still do, everytime I read it. I thought the Mini-Series was actually pretty good and Gary Sinise was an excellent Stu and suprisingly Rob Lowe was a very believable Nick IMO.
IT - comes a close second, again I got myself in with the characters in the book and its one of those that as you start to reach the end of the book you are torn between slowing down cos you don't want it to end, and finding out what happens.
I've just finished reading From a Buick 8 and may start a thread on that in a minute to see if anyone else liked it
