You could say that van Vogt's rather good Voyage of the Space Beagle is sf horror. Its rather reminiscent of Alien (which of course was novelised by Alan Dean Foster)
REF.Baylor.
Now that is a real goldie oldie, a remember buying that plus it's sequel "Hauser's Memory" in an Aberystwyth second book shop a long time ago!
Have got the novelization of the first three Alien films in an omnibus edtion, all fairly well written!
House on the Borderland by William Hope Hodgson perhaps?
Not exactly SCI-FI Horror, though, right? House on the Borderland is at least arguably s.f., or proto-s.f.
Recently they published Frozen Hell by John W Campbell which the the novel length version of Who Goes There . If you can find I highly recommend the Novelization of John Carpenter's Thing which was done by Allan Dean FosterThere are two stories that i'd like to read this year that i think fall into the Science Fiction Horror category.
Who Goes There by John Campbell. John Carpenter's The Thing is one of my all time favourite films. I'd like to read this book and also watch the film. I'm led to believe that it is still quite a good movie.
Ive read this story, it's quite nasty, One of Ellison's best stories and there is computer game version of the story which is well regarded.I also want to read "I Have No Mouth And I Must Scream" by Harlan Ellison.
