The Ruins by Scott Smith [horror (supposedly)]
Well, this was fun. I absolutely love it when too-stupid-to-live characters end up on the wrong side of the local beasty. In this novel, we have four immature and almost totally useless tourists from the USA; their recent acquaintance (also a tourist) from Germany (not quite so useless); and a random Greek tourist who has a fondness for alcohol and doesn't speak any language understood by the other five; all traipsing off to find the German tourist's missing brother in the middle of the Mexican Jungle. The only guide they have is a hand drawn map with a big X indicating a probably archaeological dig near a mine, somewhere in the middle of nowhere, provided by the brother's possible girlfriend. So, off they go - one in sandals, one hung-over, one with three bottles of tequila, and almost no other preparation what so ever. The women spend a lot of time whining, crying, wringing hands, standing around and generally being useless, along with a ridiculous number of delusions they insist on believing even through the contrary is pointed out repeatedly. Only two of the men are even vaguely practical minded and realistic. Lets just say, I spent most of the novel rooting for the local beasty, and some of it hoping the local beasty doesn't acquire "stupidity" via osmosis.
I was less thrilled with the complete lack of background about the local beasty. It's the most interesting thing in the whole story and there isn't that much information about it. You have a semi-sentient, carnivorous vine that can mimic voices and play with its prey, but the reader gets to learn nothing else about it - where it came from, why it's there, why the locals don't kill it since they seem to be able to contain it??? Too many questions!
Another annoying thing about this novel: the title is The Ruins. There is a vague reference to ruins twice (that I recall) in the novel. All the action takes place on a pretty, flower-bedecked hill, no-where near ruins - unless you consider a mine shaft (essentially a hole in the ground with a rope to lower people down) a "ruin". This is a missed opportunity! If you stick RUINS in the title and on the front of the book, I expect RUINS in the story!
The writing was flat and repetitive. There was no "atmosphere" or build up toward anticipation or creeping dread or anything like that. The plot was simplistic. The characters annoying. There were some gory scenes, but nothing was truly terrifying.
