Excellent!

This is one of those stories that you listen to and say "this is pretty good" or "I wonder where this is going" and then you say "huh? what is going on?" (referring to the oversized ants and the plants that eat people), and then bam! it all makes sense and you didn't see it coming... all of a sudden you start thinking back over the details of the story and smiling because the ending is so clever. I sure didn't see it coming and it was a real surprise. Loved it.

Great choice.
