I received this free from NetGalley and SFWA for an honest review.
This is set in The Great Human War series, although it is not really a sequel or a prequel, because it happens concurrently during the first two books and beyond. Although essentially a sci-fi story, it is really a psychological study of what happens to people who are thrown so far from home space that they don't know if they will ever get back home while family is still alive. I found it both interesting and frustrating, but ultimately satisfying.

This was a quick easy read with no great surprises.
The characters at first felt very bland, but as I read further they became more complex which certainly increased my enjoyment of the story.
