Query: Skilful writing - unoriginal story

WARNING: Possible spoiler (but it might save you $$)What you have here is your basic dead teenager formula: start with five beautiful 20-somethings, trap them in a secluded location, sprinkle in man-eating vines, then start slowly killing them off. When they're all dead you've reached the end of the book. No wonder Stephen King liked it - he's followed this template in a dozen short stories.As far as the title goes, forget it. There are no ruins. My guess is that the published knew they wouldn't sell as many books if they called it "Killer Sentient Mexican Vines," which would have been more appropriate.The two stars are for the author's craft in telling the story: Good pacing and suspense.
