"After dozens of Hollywood apartment buildings erupt in flames during a single night of terror, arson investigators Walter Sharpe and Andrew Walker are assigned to catch the serial torcher and end his spree. But then a catastrophic fire destroys a major freeway, crippling the city and forcing Sharpe and Walker to take on another massive case. Desperate for help, they know exactly who to call: homicide detectives Eve Ronin and Duncan Pavone. Together the four detectives must quickly figure out whether the freeway disaster was a tragic accident . . . or the work of a mastermind with a horrific plan. As the investigations collide, an old foe with a revenge scheme enters the fray, igniting a race against time to stop a conspiracy of deception, corruption, and murder."--
