Just reread Catch 22 recently also am reading, very slowly, The Bourne Identity. Catch 22 is a must read people!
Catch 22 is possibly the finest book ever written. Joseph Heller is the man.
Others:
J.D. Salinger
Jack Kerouac
Orson Scott Card
Aldous Huxley
Ken Kesey
Anything by those guys is gold.
and a special nod to Hunter S. Thompson.
