This debut novel—and series opener—is a blend of Christian mythology, crime drama, and arcane thriller that follows two detectives as they attempt to track down a seemingly unstoppable killer.

Ian Jelani and his partner, Lane Madigan, are Miami police detectives tasked with finding a murderer who has been ritualistically butchering criminals—drug dealers, porn peddlers, terrorists. As the two investigate the elusive executioner, they discover similar homicides across the country. The “Holy Terror,” as the media have dubbed the killer, only targets hardcore criminals. Unbeknown to the two detectives, the entity behind the gruesome murders is an angel named Thumos, Yahweh’s right hand of justice whose flaming sword of vengeance has dispatched those who do evil against Yahweh’s children for millennia. But the recent killings have not been ordained by God—and Thumos is in danger of losing his soul to darkness. As Thumos struggles with his own spiritual demons, so do Jelani and Madigan, both dealing with their own issues with accepting God’s will. Fueled by Christian beliefs—relevant biblical verses and Christian doctrine abound—this tale about the spiritual awakenings of all three characters is powerfully moving. (Christian readers will also undoubtedly enjoy the pop-culture references, like the Christian metal band Stryper.) The pacing is brisk, and Dougherty’s narrative reads like a thriller, high intensity throughout with action-packed scenes from beginning to end. The big criticism here is the wild inconsistency in descriptions of both the setting and characters. Thumos, for example, is richly portrayed: He “shook his head, and his once long, flowing white hair floated away as multiple horns began to now appear out of his head. His once human-like ears stretched into elongated leathery appendages. His mouth expanded outward, creating almost a snout, with long, white fangs.” Satan, on the other hand, is barely described at all, with the devil wearing a black robe and having “grotesque fingers” and “grotesque appendages.”

Faith-based speculative fiction fans should enjoy this tale of an angel vigilante’s glorious journey.
