Nope. You've discovered the best one. The only way for you to go from here is down.

That's maybe my favorite SF novel. I also like Le Guin, Philip K. Dick, and Kim Stanley Robinson as far as SF authors.

Book of the New Sun has a lot of fans on here but I didn't like it nearly as much as 5th Head. Interesting and worth reading, though.
