This was an enjoyable space opera. Engrossing, suspenseful. Interesting characters. However, it seemed to lack depth. No world building to speak of, no history or back story to explain what was going on in that universe. That's why it's only three stars for me. I will read the next in the series, but I may not bother to read this one again. It just doesn't have the kind of complex fabric that would bring me back again and again.
