Pyromancist (Seven Forbidden Arts 1)

He's playing with fire. One of them will get burned.

At the same time as mysterious fires rage through Clelia d'Ambois' home village in Brittany, France, she starts sleepwalking. Daughter of a Japanese orphan, Clelia's heritage is riddled with dark secrets that threaten anyone she loves. In a recurring nightmare she sees Josselin, the haunted man who abandoned their village nine years earlier, come for her, but she doesn't know why. All she knows is that she has to run. As fast as she can.

Leader of a paranormal crime taskforce, Josselin de Arradon is called back to his hometown with a mission-find and kill the firestarter responsible for Larmor-Baden's blazing destruction. Sensing that Clelia is the key to solving the crime, Josselin kidnaps her to use her as bait. The battle doesn't turn out quite as he expected. Nothing could have prepared him for the truth, or the depth of his desire for his prisoner.
