This is a zombie apocalypse story that is slightly different from the Walking Dead. Extinct is a story that starts with Peter Kirkland, an 18-year old high school senior, and foreign exchange student Adebisi Obanta, who are in a survival instincts class taught by John Proctor when the outbreak begins. Walkers in this universe turn within several seconds.

Kyle Copeland and his family experience the apocalypse. The story starts two weeks in.
