A.I. Battle Fleet — Vaughn Heppner

In a desperate fight, we captured one of the machine empire's factory planets. Can we now defeat an interstellar superpower that has exterminated thousands of sentient races across the galaxy and slaughtered billions of us in the solar system?  

Not bloody likely, but Captain Jon Hawkins is on a mission. Using new warships from the factory planet, he's searching for alien allies, more battle stations to storm, and death machines to kill. He's buying us time to turn the solar system into a fortress...if he can stay alive long enough.  

A.I. Battle Fleet is the fifth audiobook in the series chronicling humanity's grim war for survival against the galactic machine juggernaut.
