Sci-fi books tend to be hit or miss for me but I liked this one. Might be because it's a novella, so it didn't drag out endlessly...or maybe it's because there weren't too many futuristic technical terms in it (even though it is set in the future). The concept was interesting and, even though it is a typical good versus evil story, I wasn't bored by it. O, and I loved the final scene. What a great way to end the book!
