While Mary lies in a glass coffin aboard a ghost train heading west, her minions await her re-awakening by bringing hordes of new souls into Everlost to serve her.

Meanwhile, Jackin’ Jill has met Jix, a fur-jacker — a skinjacker who can take over the bodies of animals, most notably jaguars. Jix serves a Mayan god who collects Everlost coins to use in his Wurlitzer, which predicts the future.

In the concluding volume of the Skinjacker trilogy, Neal Shusterman reveals new sides of the characters of Everlost, who are pitted against each other in a battle that may destroy all life on Earth.
