Kudos where they're due: the author knows how to write good ship-to-ship battle scene. That's the end of the good things I can say. The characters all seem cut from the same cloth- spunky, snarky, kinda-misfits who are always ready for the snappy repartee with a witty or cutting comeback. They're all cardboard, interchangeable. Give this one boobs; give that one muscles; give that one the captain's chair; they all sound the same. And except for the antecedent incident which led to the plot of the novel (as told in a separate novela) I cared about none of them.
In this book, the novela is broken up and interspersed through the chapters and looses all of its impact.
I say skip it. There are plenty a better indy writers out there.
