In bookshop specializing in rare volumes, an avid fan of horror fiction seizes a tome too valuable and too incredible to fathom. In the end, the man was too curious to live. . . .

A few miles away, in a Manhattan brownstone, another man learns about the explosion that left a gaping hole in the fabric of reality. Colin–he has no other name–has been an unrelenting warrior against the dark, the demonic, and the damned. A man who has angels at his side and hell staring him in the face, he has devoted his life to solving magical crimes and tracking down–and neutralizing–the perpetrators of those crimes, human and nonhuman alike. Now Colin is about to team up with a beautiful Native American a long way from home and a tough NYPD detective who seems to be immune to magic. Together, in a funhouse of evidence and apparitions, they are chasing a killer and untangling a tale that leads from the infamous Vlad the Impaler to a dead twentieth-century occult author and his gorgeous daughter–who is as seductive as the devil himself.

Mr. Twilight combines the mystical and the mysterious, the supernatural and the primitive, in a rich, steamy brew of otherworldly adventure.
