Arson investigator Kade Decker doesn't believe in psychics -- not even when they show up in the form of his childhood friend. When Savannah Dawson keeps turning up at the scenes of a serial arsonist's crime, Kade begins to suspect her. Then he ends up shielding her from a stalker determined to drive her out of his protective arms. As the casualty count rises, the two wonder who the stalker's real target is. Jan Hambright's On Fire (4) is a chilling glimpse into the mind of a psychotic person fascinated by fire and consumed with revenge.
