Jack, a sometimes humorous, sometimes philosophical ex-special operations pilot and soldier is one of the few left to struggle through the desolation left in the aftermath; seeking to survive as a new ferocious species emerges from the rubble, hungry and unrelenting.

Or will the hordes that now own the night prevail, forever removing the last of mankind from existence? Humankind was once at the top of the food chain. But that has now changed.
