Dark Intelligence - Neal Asher

Thorvald Spear wakes in hospital, where he finds he's been brought back from the dead. What's more, he died in a human vs. alien war which ended a whole century ago. But when he relives his traumatic final moments, he finds the spark to keep on living. That spark is vengeance. Trapped and desperate on a world surrounded by alien Prador forces, Spear had seen a rescue ship arriving. But instead of providing backup, Penny Royal, the AI within the destroyer turned rogue. It annihilated friendly forces in a frenzy of destruction, and, years later, it's still free. Spear vows to track it across worlds and do whatever it takes to bring it down.
