It was total chance that I stumbled upon Scythe by Neal Shusterman, but I was instantly engrossed. While the following two books aren't quite the same, the world-building in Scythe is truly a wonder to behold. I initially read the novel over a year ago, and have read it many times since. I've recommended this book to many people, all of whom enjoyed it as much as I did. I recommend this book to you, also. Even if Sci-Fi is not your thing, this book may be able to change that.
