AI Fleet Series by Isaac Hooke

A fleet of warships operated by the digitized minds of former humans. An unknown enemy lurking in the dark of space. The one man who hopes to conquer them both. Jain was the lieutenant commander of an elite SEAL team. He was accustomed to order and discipline, which he used to give the men under his command that particular brand of killer instinct his unit was known for. But one day that semi-comfortable, ordered life ended when he opened his eyes to find his body replaced by a starship... moreA fleet of warships operated by the digitized minds of former humans. An unknown enemy lurking in the dark of space. The one man who hopes to conquer them both. Jain was the lieutenant commander of an elite SEAL team. He was accustomed to order and discipline, which he used to give the men under his command that particular brand of killer instinct his unit was known for. But one day that semi-comfortable, ordered life ended when he opened his eyes to find his body replaced by a starship. His mind had become its AI core. He is somewhere in deep space. Most of his systems are badly damaged. He has no memory of how he got here, or what his mission is. Evidence points to an attack by an unknown entity. He finds other damaged vessels in the vicinity and reactivates them. They, too, have no memory of the events leading up to their current situation. Jain, thrust into a leadership role, soon learns that commanding a fleet of starships isn't all that different from leading a platoon of SEALs. It helps that his database is chock-full of tactics and military strategies gleaned from every space battle humanity has ever fought. As he and his fleet explore their surroundings and slowly piece together what happened to them, they realize their attacker is not from any human system. And that any misstep means not only the loss of his fleet, but potentially the destruction of humanity itself. less

Jain thought he'd never go back. Ten years had passed since he last had dealings with humans and their machines. He was happy. He'd built a base for himself and his Void Warriors around the barren moon of a gas giant, where they planned to live out their immortal days in peace. And then humanity came looking for them. Hunting them. Now they have no choice but to return. But what they find waiting for them in human territory will make them wish they'd never left their new home.

Jain, a former SEAL whose mind is now the AI core of an advanced alien warship, has agreed to broker peace between humanity and the extraterrestrial race known as the Mimics. Unfortunately, a new breed of alien has decided to crash the party. These newcomers, part of the hostile Link empire, aren't very happy humanity is trying to coax a former member species into signing a treaty... moreJain, a former SEAL whose mind is now the AI core of an advanced alien warship, has agreed to broker peace between humanity and the extraterrestrial race known as the Mimics. Unfortunately, a new breed of alien has decided to crash the party. These newcomers, part of the hostile Link empire, aren't very happy humanity is trying to coax a former member species into signing a treaty. Jain and the Void Warriors have to fight off this new threat while struggling to salvage the smoldering ruins of the peace talks. Things certainly don't look good, not just for themselves, but humanity: if they can't secure allies against the Link, Earth will eventually be crushed. Some days, having your mind stored in the AI core of a starship just isn't all it's cracked up to be. Contains no sex scenes, one curse word, lots of space battles, some hacking, and an uncomfortable first date. less
