Johnny Blaze has finally been exorcized of his demonic tumor, but it lives on as something new and sentient, a dark mirror of both him and his bike...a creature known as EXHAUST. As Johnny and Talia Warroad head toward Chicago — a city known for the blood of its slaughterhouses, a city they believe is central to the Shadow Country conspiracy — they’ll be pursued by Exhaust and the dark forces he manifests.
