I was gifted this ARC from the author/ Narrator for a honest and unbiased review. Overall the story and the plot were well written. The narrator had a easy listening voice and allowed the various characters voices to be distinguishable. The only negative I would have would be what I think is a lack of naming imagination. Many of the senior officers names as well as the names of a lot of the ships, were taken from our history from several hundred years ago. Since this story was based on 400 years in our future, I would think that there would have been different military heros  or battles whose names could have been used.
