American war hero Marine Staff Sergeant Natalia Falto has given her all and then some fighting the alien invaders. Made a prisoner of war in the fighting on Guam, she suffered at the clutches of alien scientists, losing both legs, an arm, and her ear. The psychological damage was even more devastating. Her replacement limbs may have made her whole in body, but all the tech in the world could not fill the gaps in her soul.

And the world is about to learn that it is nearly impossible to keep a good Marine down. When the US downs a massive alien ship in Greenland, they sent in the Army Rangers and the elite all-ASHUR Omega Force. They also sent a secret weapon, a person with experience living with the aliens for months during her internment-Natalia Falto.

The US isn't the only nation making a grab for the alien ship. The UK's elite Royal Marines, 45 Commando, beat the US to the ship. While the Americans and British square off, it becomes clear that the alien Fish have insidious plans of their own.

With the British and the Americans at each other's throats, and in their enemy's sights, their best hopes lie with the one person who is riding the tides of her redemption!
