Flash and bones / Kathy Reichs.

Enhanced descriptions from Syndetics:

Kathy Reichs -- #1 New York Times bestselling author and producer of the FOX television hit Bones -- returns with a riveting new novel set in Charlotte, North Carolina, featuring America's favorite forensic anthropologist, Dr. Temperance Brennan.

Just as 200,000 fans are pouring into town for Race Week, a body is found in a barrel of asphalt next to the Charlotte Motor Speedway. The next day, a NASCAR crew member comes to Temperance Brennan's office at the Mecklenburg County Medical Examiner to share a devastating story. Twelve years earlier, Wayne Gamble's sister, Cindi, then a high school senior and aspiring racer, disappeared along with her boyfriend, Cale Lovette. Lovette kept company with a group of right-wing extremists known as the Patriot Posse. Could the body be Cindi's? Or Cale's?

At the time of their disappearance, the FBI joined the investigation, only to terminate it weeks later. Was there a cover-up? As Tempe juggles multiple theories, the discovery of a strange, deadly substance in the barrel alongside the body throws everything into question. Then an employee of the Centers for Disease Control and Prevention goes missing during Race Week. Tempe can't overlook the coincidence. Was this man using his lab chemicals for murder? Or is the explanation even more sinister? What other secrets lurk behind the festive veneer of Race Week?

A turbocharged story of secrets and murder unfolds in this, the fourteenth thrilling novel in Reichs's "cleverly plotted and expertly maintained series" ( The New York Times Book Review ). With the smash hit Bones about to enter its seventh season and in full syndication--and her most recent novel, Spider Bones, an instant New York Times bestseller--Kathy Reichs is at the top of her game.
