Flashover — Suzanne Chazin

Fire marshal Georgia Skeehan sifts through the ashes and uncovers the many layers of friendship and betrayal in this second thriller in the series. ....

In this novel, Georgia investigates two mysterious deaths, both involving victims of fires that show signs of "flashover" - the vicious and overwhelming combustion of a room and its contents by simultaneous ignition. She suspects the connection between the two might be disputes over line-of-duty compensation for disabled firefighters. But a hunch won't win a conviction in anyone's court of law. Georgia is left grasping for straws when the bottom of her life drops out: someone close to her disappears - from an apartment with a few odd and chilling clues - and a man found at the scene is none other than Georgia's boyfriend and fellow marshal, Mac Marenko. Betrayal, both private and professional, has never hit so close to home. Georgia finds frightening evidence that greed and deception are the cause of these recent deaths and will perhaps be the cause of one more to come - her own.
