Magical cults are better left alone. Especially when they've got friends in high places. When twenty-three bodies are discovered on the edge of the Fallout Zone, the FBI calls in Ruby Callaway and Colton Roark to investigate. From the powerful dark magic branded into the bodies, Ruby quickly determines those responsible: the Crusaders of Paradisum. Which is impossible, considering Ruby killed their Crusading Prophet, scattering the cult to the wind over a century ago. But some people just don't know when to stay dead - especially when they've made new friends in powerful places. And that's a problem Ruby needs to fix. Before it kills her first.
