Null-A Three

Description for NULL-A THREE by A E Van Vogt:

One of the immortal classics of science fiction is A E Van Vogt's THE WORLD OF NULL-A.  Published in the Golden Age of SF, it shook the science fiction world with its astounding hero, Gilbert Gosseyn, who apparently could not be killed, and with its presentation of General Semantics as applied to the future of all humanity.

An SF landmark, in print to this day, it was followed by an equally remarkable sequel.  Now, in response to the myriad admirers of these ground-breaking concepts, Van Vogt has written the third and last book in the Null-A universes.

Meet again Gilbert Gosseyn, the man with the extra brain who staved off disaster for the Solar System, as he finds himself launched on his greatest challenge---a showdown with the originators of cosmic civilization.

NULL-A-THREE is destined to become an instant classic---a mind-boggling galaxy-spanning adventurer!
