A mass murderer hides somewhere in the Great Smoky Mountains National Park. He has a deadly secret. And a bomb. Tracker Aroostine Higgins and Special Agent Patton River Banks have a strained relationship. But, when Aroostine picks up the trail of a fugitive during a visit to Clingmans Dome, she and the National Park Services criminal investigator have no choice but to work together. Alan Steven Reynolds has been on the run for years-ever since he helped engineer one of the country's deadliest bombings. When Roo finds evidence that he's hiding out in the park's 800 square miles of dense forests, she and Patton join forces to find him. They aren't the only ones looking for Reynolds, though. He's been active during his time underground, and a new client has explosive reasons to stop him from talking to the authorities. Roo and Patton are in a race against time and a shadowy enemy. They need to bring Reynolds in before his partner brings him down, along with anyone else who happens to be in the woods. Clingmans Dome is the sixth book in USA Today bestselling author Melissa F. Miller's smart, fast-paced Aroostine Higgins series.
