1879, Golder's Rock. On a clear, moonless night in high summer, the stifling heat coils around a small town in the heartland of the Arizona Territory. Not a single lick of a breeze whistles through the dark, dusty main road, as silent as death itself. After tracking down an old enemy for eight long years, lone bounty hunter Lee "Blackjack" McCarthy has finally pinned down his target—his eyes set only on vengeance for a past he can't forget. But when the town mayor is ruthlessly murdered on that fateful, sweltering night, Lee's plan suddenly stops dead in its tracks. Suspected of the killing, forced to remain in town under watch, and desperate for the opportunity to catch his quarry, Lee has no choice but to work with the townsfolk he trusts—each with their own buried pasts and agendas—to reveal the truth and clear his name.
