From the first few pages I knew what the "twist" would be.... I was right, but there was a second "twist" I didn't see until almost the end of the book - granted the second twist was introduced late in the story. This is actually a really good short story thou, even if it was predictable. It almost has a original Twilight Zone feel too it, or maybe a Starship Troopers feel (if everyone was humanoid). It's not hard to spot the so called "twists", which I think makes it part of the charm of the story. It's a pretty fast read, so If you have a few free minutes, like Twilight Zone style twists - I say give this a read.
