Valiant Light is the sixth and final book in the Demon Trappers series by Jana Oliver. It was released on November 25th, 2017.
Master Demon Trapper Riley Blackthorne’s life is about to change . . .again. With her wedding approaching, as well as her fiance's investiture as grand master, she’s got a lot on her plate. When she allows a high-level demon to remain at large, one who claims to be free of Lucifer’s hold, she knows that decision may come back to haunt her.
Denver Beck is facing two major events: taking his vows as a grand master, and as a husband. He’s nervous about the first, but eager to say, “I do!” His worries about their future are confirmed when a Czech city is buried in brimstone, killing all its inhabitants. Was this Hell’s doing or is some other entity at work? One way or another, he’s been tasked to find out.
When Riley is summoned to Rome to answer for her actions, Beck insists on joining her. Even as she challenges the Vatican’s centuries-old views on Hellspawn, bringing her loyalties into question, more cities are destroyed. From everything they’ve seen, the killer is unlike any demon they’ve ever faced. This one, even the angels fear.
