A Void's plot follows a group of individuals hunting a missing companion, Anton Vowl. It is in part a parody of noir and horror fiction, with many stylistic tricks and gags, plot convolutions, and a grim conclusion. In many parts it implicitly talks about its own lipogrammatic limitation: illustrations of this including a missing subdivision 5 (of 26), and calling its main protagonist "Vowl". Individuals within A Void do work out what is missing, but find difficulty discussing or naming it as it has no word or form that conforms to its author's constraint. Philip Howard, writing a lipogrammatic appraisal of A Void in a British daily journal, said, "This is a story chock-full of plots and sub-plots, of loops within loops, of trails in pursuit of trails, all of which allow its author an opportunity to display his customary virtuosity as an avant-gardist magician, acrobat and clown."
