April Books 23) Stress Pattern
A story of a bloke who crashes on an alien planet where strange creatures live, some of them formed by his own thoughts and desires. (Solaris meets "A Martian Odyssey" only nothing like as good.) His fantasy woman is created for him and it doesn't work out. Only 160 pages, thank God.
April Books 24) Judge Dredd (the book-of-the-film)
I've never more than skimmed 2000 AD but was aware of the basic set-up of Dredd's world; I have not seen the 1996 movie starring Silvester Stallone. Difficult to, er, judge what Barrett's input to the final product is (he did not write the screenplay) but I felt that I missed the broad sweep of scene-setting which is necessary in a novelisation of this kind; no real sense of landscape or background. There are some nice inserts from a future historian commenting on the story as past history, including one (perhaps despairing?) piece near the end complaining that it is all made up. Barrett also wrote the novelisations for the Dungeons and Dragons movie and Barb Wire, but I will not rush to acquire either.
There must surely be numerous other authors of similar prominence and age to Barrett who would qualify as Authors Emeriti (or Emeritæ). Maybe I was just unlucky; I will concede that a book's availability from Bookmooch may not be a good indicator of quality.
