FDNY marshal Georgia Skeehan returns in this new thriller from the authorwho "will do for firefighting what Patricia Cornwell did for forensic science" (Lee Child, #1 New York Times-bestselling author).   Georgia Skeehan, a marshal with the New York City Fire Department, investigates the deaths of two doctors, both victims of fires that show signs of a "flashover"--the overwhelming combustion of a room and its contents by simultaneous ignition. Each worked on the board approving "line of duty" compensation for disabled firefighters.   Georgia is left grasping at straws when her best friend, a detective with the NYPD, disappears, and Georgia's boyfriend and fellow marshal is found in her blood-spattered apartment. Betrayals--both private and professional--have never hit so close to home. Georgia finds frightening evidence that a long-ago tragedy may be behind these vengeful acts. And she must stop them before they consume their ultimate target--Georgia herself . . .   Praise for Suzanne Chazin's debut novel, The Fourth Angel:   "Chazin dazzles with her knowledge of pyrotechnics and comes up with plot twists aplenty." --People   "A red-hot debut." --USA Today
