When an airborne “zombie” plague is released, bringing civilization to a grinding halt, the Smith family, Steven, Stacey, Sophia and Faith, take to the Atlantic to avoid the chaos. The plan is to find a safe haven from the anarchy of infected humanity. What they discover, instead, is a sea composed of the tears of survivors and a passion for bringing hope. For it is up to the Smiths and a small band of Marines to somehow create the refuge that survivors seek in a world of darkness and terror. Now with every continent a holocaust and every ship an abattoir, life is lived beneath a graveyard sky.

With the world consumed by a devastating plague that drives humans violently insane, what was once a band of desperate survivors bobbing on a dark Atlantic ocean has now become Wolf Squadron, the only hope for the salvation of the human race. Banding together with what remains of the U.S. Navy, Wolf Squadron, and its leader Steve Smith, not only plans to survive—he plans to retake the mainland from the infected, starting with North America.
The next step: produce a vaccine. But for do that, Wolf Squadron forces led by Smith’s terrifyingly precocious daughters Sophia and Faith must venture into a sea of the infected to obtain and secure the needed materials. And if some of the rescued survivors turn out to be more than they seem, Smith just might be able to pull off his plan.
Once more, exhausted and redlining Wolf Squadron forces must throw themselves into battle, scouring the islands of the Atlantic for civilization's last hope.
