Quinton Zane is back. Jack Lancaster, consultant to the FBI, has always been drawn to the coldest of cold cases, the kind that law enforcement either considers unsolvable or else has chalked up to accidents or suicides. As a survivor of a fire, he finds himself uniquely compelled by arson cases. His almost preternatural ability to get inside the killer's head has garnered him a reputation in some circles—and complicated his personal life. The more cases Jack solves, the closer he slips into the darkness. His only solace is Winter Meadows, a meditation therapist. After particularly grisly cases, Winter can lead Jack back to peace. But as long as Quinton Zane is alive, Jack will not be at peace for long. Having solidified his position as the power behind the throne of his biological family's hedge fund, Zane sets out to get rid of Anson Salinas's foster sons, starting with Jack.
