A husband and wife brought together by magic strive to stop a war of the worlds in an epic adventure of hope, sorcery, and secrets by Wall Street Journal bestselling author Jeff Wheeler.

What humankind feared the most has come to pass: the Awakening of the Aesir, an ancient race who rose with an implacable vengeance to wage war on mortals through bombardments and plague. Two people gifted with magic and ingenuity strive to stop them.

Professor Robinson Hawksley, an elocutionist in the Invisible College, prepares to exhibit his invention to the world. Using sound to defeat the enemy could change the course of the war. It's invaluable to the military. Even more so to a conniving rival who'll do anything to prove its patent as her own. An extraordinary obstacle could stand in the way: Robinson's new wife, McKenna, robbed of her hearing by an Aesir scourge, is otherwise blessed with mysterious powers she's only beginning to comprehend. She's also harboring a secret that could get her killed.

As a very human war escalates inside the Invisible College, a supernatural one with the Aesir rages outside. But are love and sorcery enough for Robinson and McKenna to conquer both?
