What would you do to save a world? Brand sees demons. They are a lot less rare than you might think. In fact, they are everywhere if you know what you're looking for. Unfortunately for Brand, that's the least of his problems. His mom thinks he's crazy, but he and his friend Aaron have discovered an entire world underneath our own -parallel and invisible. It is a land of darkness and light in stark contrast, where good and evil show their true face. When the darkness controlling the underworld of Annwn reaches up to threaten those closest to him, Brand has to decide whether to protect his family or return one more time to repair the damage he has caused with his meddling. To right what has been wronged will cost Brand more than he realizes, for his quest will require him to face that which cannot be faced, and defeat that which has never been defeated. To succeed, Brand will have to face down Annwn itself.
