Burn Dragon Burn by Julia Mills

The Dragon Protection Agency- Shiny badges, rock-hard scales, and a whole lotta fire they know how to use.

Six murders in eighteen months. No clues except the bodies he leaves behind. The murderer in all the papers is called the Yellow Ribbon Ripper, and he’s due to strike again. But who will be the next victim? Where will he leave the body?
The clock is ticking. The killer is on the hunt.
Can Nat see where he is? Can Rafe blaze the trail in time?

Fate Will Not Be Denied…but then again, She’s never been chased by a serial killer.
