Everfound — Neal Shusterman

While Mary lies in a glass coffin aboard a ghost train heading west, her minions are awaiting her re-awakening by bringing lots of new souls into Everlost to serve her. Meanwhile Jackin' Jill has met Jix, a fur-jacker -- a skin jacker who can take over the bodies of animals, most notably jaguars. Jix serves a Mayan god who collects Everlost coins, and has his own agenda. 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.
