I thoroughly enjoyed this book. Alex did a great job with the second book in the series. In fact, I still haven't read the first one (but I will now for sure). He did a great job in giving just enough pertinent information that I never felt lost even though I started in the middle of the story.
Byron and Athee were both likeable characters and I found myself rooting for both of them. The tech was great! I loved the idea of telejumping ships for the mode of space travel. That may indeed end up the only way we can successfully travel between the stars.
