«Prelude to Mayhem» by Edward Aubry

In the ruins of his world, Harrison Cody follows a mysterious voice on the radio as he and his pixie sidekick travel on foot across a terrifyingly random landscape.

They discover Dorothy O'Neill, who has had to survive among monsters when her greatest worry used to be how to navigate high school.

Together they search for what remains of Chicago, and the hope that civilization can be rebuilt.
