Loved this character driven military space opera, revolving around energy systems called lines, worked by linesman, that may be sentient. Audio was excellent.
If you like sci-fi, you'll love this book. I couldn't put it down.
The concept is original and super creative. Plot moves along nicely with an energy that flows along with the events. Characters are lifelike and real, and the protagonist stays consistent to his nature throughout the story. The writing is simple and elegant; it's so good that it moves out of the way to present the story.
PS - If you read it, you'll find out what line 8 does ;)
