An unknown force threatens Heaven and Hell, along with every soul on Earth. Three unlikely heroes join together to restore universal balance. Will their shared adversary initiate an Apocalypse before they're able to uncover the truth, or will they rise to a calling that has, from the beginning of time, been Cast in Blood?

Chaos has taken over, wreaking havoc not only across the globe but also throughout Heaven and Hell. The next apocalyptic seals have been breached, and the leaders of the ethereal realms are paying the price. With tensions high and defenses at an all-time low, Polly, Lenny, and Drew continue to hunt down the evil behind it all. Millennia-old secrets rise to the surface, testing friendships and pushing loyalties to their breaking points. With the clock ticking and uncertainty in the air, will enough time remain to unravel a curse that the darkest of forces have Cast in Fire?

The final seals of the apocalypse are within the enemy’s grasp. Our trio—the demon, the shapeshifter, and the succubus—continue to battle the djinn hell-bent on world domination. With God and Lucifer missing, Heaven and Hell are more vulnerable than ever, while Earth has been reduced to a battleground of famine and despair. Will Lenny, Drew and Polly be able to unmask the Master and stop their evil plan? Or will the djinn succeed and our heroes find that their world has been forever Cast in Shadow?
