Cascade Failure

'My name is Daniel Cross and I was bored as hell living aboard the IPC Wanderlust. Space was boring, living with the same people was boring and having to eat the same food was boring. Everything changed for me though the day that we answered a distress call from an unknown ship called the Saturn. If I have to deal with the ship's AI for too much longer though I don't know what I'll be capable of...'
With nobody on board, the Saturn was a bit of a mystery and I felt as though I was destined to live my life in perpetual loneliness and boredom the day that my ship left me stranded aboard the derelict with no hope of rescue and little chance of surviving long term.
Finding that the Saturn was also a Space Corps ship like my own the Wanderlust, though from some time in the future it seemed, the ship's artificial Intelligence helped somewhat sarcastically and very annoyingly to get me enlisted as the one live crew member aboard the vessel. Little did I know that this would mean having to carry out the orders given by the AI, being either direct or coercive.
Eventually finding that the previous crew of the Saturn were still dotted around the system in a sense, my orders required me to save them from the planets that they'd been sent to wage war and ultimately had been stranded on.
Using the technology of the future combined with the training and tactical knowledge of my past, I could see things a little differently to those who I interacted with and as such brought a new dynamic to battles waged in the present, though with futuristic tech.
