The World of Null-A - Sequels

Sequels

The World of Null-A was followed by the sequels, The Pawns of Null-A (also known as The Players of Null-A) (1956) and Null-A Three (1984).

In 2008 John C. Wright wrote a new chapter to the story of Gilbert Gosseyn, Null-A Continuum, in the style of van Vogt.
