"A century after an alien attack nearly destroyed the entire United Planetary Alliance, the enemy has returned. Isolated on the outer rim, daring Captain Mitchell and the crew of the USS Defiance are about to become the first line of defense." Why? The UPA have had a century to prepare for another alien attack and they're caught unawares? They have no AI defenses? No robot defenses? This author like so many other sci-fi authors (I'm looking at you David Weber) has simply not thought it through. Naturally you want a human element in your story, but that doesn't mean the story has to be brain-dead and reliant on the same thinking, and the same technology, we use today! Nor on the same unimaginative bullshit stories everyone else has already told at least twice.
