Magic Rune Academy, Book 4 - Landon Scott

War has come to the Rune Realm. The Goddess Mother has returned, but there is nothing divine about her.
Nate has survived everything thrown his way: powerful professors, deadly trolls in the Forest of Dreams, and the cutthroat chaos of the Questing Games. Each time, he's defied the odds, finding a way to triumph.
But this is different. This is war.
With Grishna missing, and dozens of other runics vanishing without a trace, Nate and his companions set out to uncover the truth. Their journey will lead them across the Realm, into the arms of unlikely allies, the jaws of buried secrets, and face-to-face with a power unlike any they've encountered before.
Classes are over. The Games are done.
The real fight has just begun.
