Seriously, suspension of disbelief is ruined within the first few chapters. Take a Captain, whose father and grandfather are both admirals, although the grandfather is deceased. The grandfather just so happened to be commanding the fleet that was attacked to start the war. (There has to be a war, naturally). Combine this with a pilot who, supposedly, can fly anything ever built, even a ship with controls in no known language, and in unrecognizable configurations. And, let us not forget a small craft mechanic who seems to be the second coming of Montgomery Scott and Spock's love child, whose intuitive genius allows him to repair/fix/jerry-rig/Macgyver any system, including completely unknown systems with unknown technologies all before lunch. Combined with a squad of special forces troopers, who were previously commanded by the aforementioned Captain, gather together in a boarding pod launched in the midst of battle. A boarding pod, launched not to board disabled ships, instead to evidently Dirty Harry their way mid-battle to board enemy ships that are still fully active, retaining fighter coverage and weapons capability. Oh, did I forget to mention that our Stalwart Captain is evidently on the outs with unknown parties within his own command structure?
Our heroes, placed in this unruly cauldron of Authorial fiat manage to:
A) Outfly purpose built fighters, avoid being shot down by both sides.
B) Manage to miraculously escape to an abandoned enemy salvage ship, fully working, fly aforementioned salvage ship to his grandfather's flagship.
C) Miraculously said flagship, sitting there for an indeterminate (est 30+) number of years, has yet to be salvaged by any errant unabandoned salvage ships.
D) Our A-Team of heroes then manage to board said flagship, recover it's main data core/computer, several plasma cannons, supplies, fighters, oh and Scott McSpokadoodle puts together an EMP CANNON, handheld, naturally, that they use to take out some recon fighters.
But wait! We are not done! Said EMP cannon has shorted out the cloaking device of an abandoned alien super-ship, complete with Shields of Impregnability, Cannons of One-Shot One Kill, Improbability Drive of Instant Movement, and Mysterious Magical Compartments (haunted).
Instead of the author starting out with his protagonists in control of said alien ship, whose discovery could be filled in as needed for narrative sake, he seems to have decided to come up with the most improbable set of circumstances possible to equip his protagonists with the necessary tools to tell his intended tale.
