Pros: unique storyline, fed my love of space/stars/the universe, good dialogElder and Amy were easy to like. The characters were developed to the point that their actions made sense. I feel like the author left a bit too much out of Elder's past. I would have felt more for him if I knew more about him.Cons: transparent plotI don't even know if that is what I didn't like fully. I knew who the villain (not that he was all so bad) was from the first time we met him, I figured out the mystery, I knew the big details and I don't think I was supposed to at the point I learned them. That being said, I would recommend this book. It's different enough from what's out there that it deserves to stand above many of the others.
