Bixby was 12 years old when the world ended. A mysterious mist had blanketed the earth, turning most of the world's population into blood-sucking monsters. The remaining survivors plummeted to the bottom of the food chain. Now, eight brutal years later, these survivors face another challenge-a new threat is turning the tide of war between humans and the infected. This threat may very well spell doom for the last vestige of humanity. In a race against time, Bixby and her crew battle to stop the decimation of the human race at the hands of these new mutations. They are the last strain of resistance.
