Blaze by Fiona Davenport

Pax “Blaze” Driscoll was an expert on fires, but he never expected to fall for a woman in the middle of a flaming building. Especially not after she accidentally set fire to a Hounds of Hellfire MC warehouse.
Courtney Cartwright’s roommate disappeared without a trace after she stole from the wrong people. They’re out for blood…and Courtney is smack dab in their crosshairs. But Blaze will burn down the world before he lets anything happen to his woman.
