A secret buried in the Antarctic.
A puzzle unsolved for thousands of years.
And a Brooklyn-born Master Gunnery Sergeant who's royally pissed that he has to babysit the researchers sent to figure it all out.
Patrick "Wic" Finnegan's last op as a Marine Raider before retirement sends him to the frozen Ellsworth Subglacial Highlands. The only reason he's here?
He owes a favor to an old friend-but that doesn't mean he has to like it.
When Wic finally sees what the team has uncovered, he can't believe his eyes, nor is he prepared for the violence to come.
Soon, the portal opens and unleashes a storm of unbridled fury upon humanity.
From the Antarctic tundra to the streets of Manhattan, Wic and his team will be pushed to their limits as they fight to hold back Earth's ultimate threat.
The odds are against them. Governments are toppling. And the Earth is falling into ruin.
