I tried reading Gaiman solo books, last one was "American Gods" => didn't like it, maybe a translation issue.

That was the book which woke my interest in Gaiman's works.
A fabulous book but everyone's tastes are different so I am not surprised you don't like it. Maybe you should try to read the english version?

Just say that Terry Pratchett writes very good books on philosophy disguised as fiction to persuade people to read them

I discovered so many things while reading Science of the Discworld <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
