Not the usual type of military SF I’m use too, but Fortunes Pawn was a very good venture off the beaten path. Yes, it is listed as military SF on goodreads but it lacks the actual military appeal as most would. However it has hints of it in there. It was fun to read.
You are following the protagonist Devi Morris (Ms. Morris) as she takes on a security position (which she normally hates) on the infamous “Glorious Fool.” The ship crew is filled with a diverse selection of Humans. The ship is also full of secrets that are worth killing for. The average mercenary last just under one tour of duty on the Glorious Fool. Ms. Morris plans to see her contract all the way to the end in order to receive her wish to join one of the most elite forces in the universe, The Devastators.
