Query: He completely changes the backstory . . .

It seems that I'm the only one on the planet who hated Ash Ock and Paratwa. Liege Killer is definately a groundbreaking novel. The problem occurs in that he completely changes the backstory (which was excellent) to a half-arsed alien novel, instead of a scientific breakthrough. This discontinuity is similar to the storyline changes between the movies Highlander and Highlander II.I cannot recommend either Paratwa or Ash Ock, as they are very poor sequels to a fantastic novel, solely due to the drastic change in the storyline.
