Ali has been on her own for three months, hiding in the safest place she could find. Hiding from the infected freaks that she considers no longer human, as well as those that survived the outbreak.

Fall is just around the corner, and finally unanswered questions drive her from her hiding grounds. She needs to find out what happened to her friends, her family, the world. She needs to find out why she's changing. She sets out on her quest for answers, traveling across the southern United States to find out what makes her different from all the others that were infected.
