The first Celestial War ended long ago. Now, its story is waking again. Elias's message lingers in Matt's mind. The mysterious monuments, the pulsing yellow light on the holographic display; they won't leave him alone. He knows they're connected to the ancient Book of Celestial Wars, but how? And why now? It's not just the looming threat of another creature attack. Not just the rogue government tracking their every move. Not even the mysterious visitor whose true intentions remain unknown. No, something much worse is coming. The Demon Tide is rising. The Shadow Government is growing bolder. And whatever they're hiding could change the world forever. Despite this (or perhaps because of it), Matt must find the courage to stand, the strength to trust his friends, and the resolve to embrace the truth about who he was meant to be... A Demon Tide warrior.
