The Privateer: Flight Engineer, Book 2

Flight Engineer Peter Raeder saved his ship, but his heroism didn't follow the rulebook. The reward was a reprimand and a desk assignment - a fate worse than death for Raeder. Fortunately, a Marine General offers Raeder command of a hidden base deep in hostile space from which he will attack enemy shipping, a mission preferable to exile to an office cubicle...even if his chances of surviving this assignment are very nearly zero.
