A long shot this, as Bookfinders and AbeBooks search engines have drawn a blank.
I'm trying to find a novel I once bought in the early '70s, remaindered hardback, High St shop... I'm 90% sure the title was "Survive!", Blue dustjacket, but I can't remember the author's name though I think it sounded European rather than Anglophone. Published before 1980... probably before '75 and I doubt it would have been reprinted..
It was framed around a climbing story with two men on an Alpine face somewhere, one gets hurt by a stonefall, partner leads to the top eventually. Interwoven with this there's some kind of sci-fi or metaphysical parallel story running through the book. I read it twice in my teens and couldn't make head nor tail of it! I suspect it isn't well known if at all, but somebody might have "the other copy"
I'm intrigued now more by not being able to find it to be honest, but I'd be interested to see what it was all about by reading it again. Or even just to find the author's name..
Does it ring any bells?
