Dan and Drew continue their quest for survival in the chaotic new world. Having gained a little more knowledge and weaponry, the two strike out to prepare for the coming winter and secure their base of operations. In the process, they discover a few frightening things about the former occupants of their neighborhood and the surprising existence of another person who has faced the apocalypse with a startling indifference.
Communicating via the bulletin board system, Dan meets another survivor not far away who would make a valuable third addition to their little group. His knowledge of obscure things, and seeming preparedness, leads Dan to believe that he is needed. Deciding to scoop him up in an impromptu rescue mission, the two travel north. Along the way, they discover the desolation that has been left by not only the infection, but an ongoing conflict between a paramilitary group and the surviving US Armed Forces.
As the world continues to crumble around them, new challenges and shocking discoveries will test their strength and unity. Only by teaming up with their new ally, and making it safely back home, can Dan and Drew hope to survive.
