The earth is being decimated by an alien species that is harvesting all of its technology. A traveling band of humans is trying to salvage as much history as they can while staying one step ahead of the aliens.
This was a really unique book. The landscape and characters are interesting and imaginative, but definitely on the bleak side. Imagine big swaths of the earth just cut right out. And freaky aliens who are scooping up anything on earth which contains technology. That will give you an idea of just how desolate the earth is in this story.
The action centers around a group of children who are out exploring and accidentally draw the attention of the aliens. They try to evade them, but end up right at the heart of the alien enclave. I won't tell you the end because that would just wreck the story, but it's satisfying.
I recommend One Trick Pony to fans of dystopian science fiction. If you like aliens, this would be right up your alley!
