Legacy Fleet: Invincible (Kindle Worlds) (The First Swarm War Book 1)

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.
