WraithLord:
I am buying my books from Amazon, if I want them in English. Well, didn't have to order internationally yet, but pricing did not seem to be huge [sure, you can probably find them cheaper in your language at some local store or on ebay etc].
"A Cruel Wind" is a tome of 3 books from Dread Empire, they are supposed to be the best. I have to buy remaining ones.
I also have that 1,2k pages one-tome edition of Amber Chronicles
Waiting for some global internet shortage :P
Terry Pratchett should be easy to get everywhere [but I'd suggest again reading it in English], he is really popular. Start with the first 2 tomes. And after it anythign with Rincewind is great
But yeah, they get a bit similar in style.
