Blaze (The Firefighters of Darling Bay #1)
Lila Ashe, Rachael Herron

Tox Ellis is the hazmat expert at the Darling Bay Fire Department, and he knows about harmful substances. He knows what gases to keep apart to prevent explosions. Why, then, can't he seem to stay away from Grace, the woman who seems to think he needs fixing?
Is Darling Bay ready for the chemical reaction Grace and Tox generate whenever they're in the same place at the same time? And who will be standing by to put out the flames?
