Tyrone 'Tim' Middleton had been on his way out. With twenty years of military service under his belt, it was time to settle down on a colony somewhere and start the next phase of his life. But without warning, the Empire of Man withdrew its support of the Confederated Spineward Sectors, taking the vast majority of high-value military assets - including capable officers - with it. The would-be retiring Lieutenant Commander was improbably given a field commission of Captain, and tasked with a simple 'wave the flag' operation by his even more improbable commanding officer, Admiral Jason Montagne. So Captain Middleton set out to patrol the adjacent Sectors, and carry out his orders to the best of his ability. But, as is so often the case, one thing leads to another and Middleton finds himself and his ancient warship, the Pride of Prometheus, caught in quandary after quandary as the shadows of a Sector-wide conspiracy loom wherever they turn. The further down the rabbit hole he goes, the less he likes what he finds and his simple patrol mission soon turns into something much, much larger. With a crew of rookies and society's unwanted - including a pair of teenagers from a world very different from his own - Captain Middleton will discover one simple, incontrovertible truth: In life, there is no middle ground.
