Like her mother, she will defend against those that might cause harm to the innocent by using the gifts that have been bestowed upon her by the Wispet Queen. Will it be enough to protect her?

Discovering Jario was behind the mask of antlers, Baxter and Laralynn are tasked with capturing him. One wrong turn hurls them all into a hidden world far beneath Wintergreen Mountain called Alabaster.
