From the New York Times bestselling author of Robert B. Parker's Ironhorse comes a new installment in the Hitch & Cole series. An ominous storm is rolling in over Appaloosa, bringing with it a band of night riders who appear at the Rio Blanco camp, where a three-hundred-foot bridge is under construction. When Appaloosa's sheriff and deputies suddenly vanish without a trace, territorial marshals Virgil Cole and Everett Hitch saddle up to sort things out. However, Cole and Hitch have no idea of the dangers they are about to face or how far-reaching the destruction will be as the clouds over Appaloosa grow even darker.
