The aliens took her ship. Commander Halsey wants it back. For decades they were among us, silently infiltrating the power structures of society. Now the Swarm stands on Earth’s doorstep. As humanity launches a desperate counter-attack, the alien victory seems inevitable. For Halsey, this is personal. While the Fleet executes their battle plan, she leads a do-or-die suicide strike at the heart of the alien force: her own INVINCIBLE, turned into a weapon against mankind. With a few marines, a pirate ship, and an ex-lover by her side, Halsey fights to take back her command and save the human race—or die trying. She is a proud warrior. She is humanity’s last hope. She is INVINCIBLE.

Earth defeated the aliens once. Now they’re back. After the devastating attack on Earth, the Swarm fell back to regroup. Now, sooner than expected, they’ve returned to finish what they started: enslaving the human race. Samantha Avery, newly promoted captain of AVENGER, has her hands full—a paid assassin seeking her death, a renegade officer working for the Swarm, and an enemy fleet bent on the destruction of the vital Wellington Shipyards. As the Swarm launches a devastating attack against Britannia Sector, Avery finds she must seek victory on multiple fronts. But Avery is a patriot for humanity. She’s a dam standing tall against the alien flood. She’s an AVENGER.
