hehe i actually have buy the entire Sandman serial 3 times now.
Because when i read it the first time, i thought it was so great that i gave them away to someone i knew would love it too.
But then, after some years i wanted to read it again, and then i had to buy it again.
And of course the same happen again, i got a visitor that had not heard about it, so i gave it away again.
And last year i wanted to read it even one more time, so i had to buy it again.. lol
This time i have learned, and will keep them, because i think that they are so great that i probably will enjoy reading them again 5 years from now.. lol
PS. you should read some of the things from Terry Pratchet too.
He was very much inspired by Sandmans world, and kind of copied it, but he added humor to the stories. (with Neil Gaiman`s blessing)
