Palahniuk is one of my favorite writers.
I think that his books are for strong stomachs, especially "Haunted" (in Italy the title is "Cavie" literally translated in english "Cavy").
I read:
Fight club
Haunted
Survivor
choke
I counsel starting with Fight Club...
Palahniuk is a writer who should be first understood and then read
He describes our society to perfection!
