Full Blaze by M.L. Buchman

When fighting a wildfire, how far is one step too many? And what happens after you take it?

Raised in the Outback, Jeannie Clark fought bush fires in Australia and wildfires in the US. But when she uses her firefighting helicopter to rescue a wildfire photographer she finds more danger than ever before.
Cal Jackson may be an orphan and a foster child of too many homes, but he found his purpose in the heat of a wildfire. Now he fights the flames with a trained eye and a camera.
But not everything is as it seems with their firefighting outfit. The next firestorm they fly into, the covert operation could be even more dangerous than the flaming wilderness.
