How do you save the world when you can't even save yourself? Resonance Murphy cares about only one member of the world's population—herself. So, when the self-applauded master of irresponsibility moves to the Maryland Eastern Shore town of Tyne and discovers the fate of all humanity rests on her shoulders, she's more than a little irked. Thousands of years ago, seven benevolent gods drove their evil brother, Ta-gul, into a collapsing dimension. Now, Ta-gul is about to re-emerge in Tyne and Resonance is the warrior fated to destroy him. With a murderous dark magician; an ancient cult; a desperate fallen goddess; and a mysterious, tattooed young woman each intent on thwarting her by any means, Resonance must put aside her inhibitions and finally place her trust in someone besides herself. Fearful of the coming days and fascinated by the mercurial young woman, necromancer Quinn Lehrer aligns himself with Resonance. As Quinn helps the reluctant warrior run the gantlet of reality-bending trials that will give her the power to defeat Ta-gul, a series of terrible revelations will force him to decide if Resonance is truly worth aiding. As the clock ticks down to Ta-gul's ascension, the unlikely couple find themselves in a labyrinth of choice and consequence, where each decision sheds new light on Resonance's long-forgotten past, and brings the reluctant warrior closer to the moment when she will become either the savior of humanity—or the catalyst for its downfall.
