In a perfect world where overpopulation is the only problem, an elite group of unbiased assassins called Scyths are expected to “glean” the population to keep it at a manageable level. This is by far one of the best young adult sci-fi books that I've ever read. With its fast-paced plot, Scythe is a captivating story of two teenagers faced with enormous responsibility and life-or-death consequences. I have a soft spot for skillful world-building, action, and fleeting romance; this book was a masterful concoction of all three! Also, on a personal note, I have read far too many books with idiotic plot twists. I am pleased to say that this was not one of them. Get ready for an addicting read, as this book isn't easy to set down.
