Detective Jelani is a tough, veteran cop, who earned his stripes in the rough-and-tumble streets of St. Louis before relocating to Miami. His younger partner, Detective Madigan, is brash and confident. But they were never prepared for what awaits them as they try to solve these latest crimes. They are about to become embroiled in a series of cosmic events which they could have never dreamt of, even in their wildest imaginations. In a world where the angels of heaven and the angels of hell bring their ageless battle to Earth, how will these men, and their families, overcome such insurmountable challenges?

As has been the case since the beginning of time, God and His heavenly host are facing off with Satan and his hellish host. Caught in the middle is Thumos, possibly the most powerful angel ever created. He is a warrior angel, "quickened" by God for one thing: battle. And he has seen plenty of that down through the centuries. No one can match his prowess; not even the Archangels. But Thumos has become a disgruntled warrior of God, and after standing by for long enough, he can take it no more.

The earthly world of these two Miami detectives will collide with the heavenly world of Thumos. None of them know what is coming, and none of them will ever be the same again.
