The Fast Guns. The Fast Gun Series, #10

Hal Hawkins never backs down. Known as the Hawk, he's one of the fastest guns in the West. The hard-bitten lawman has traded violent boomtowns for the quiet backwater of Twin Oaks, honoring a debt to an old friend. But beneath the town's peaceful surface, trouble is already brewing; Bill Wolf and his son are determined to seize control of the surrounding range. Meanwhile, convinced that gold will soon transform Twin Oaks into the next great boomtown, a hidden mastermind is willing to spill blood to own both the land and the town.
The Hawk and his deputies will need every ounce of courage and skill to stop both threats before Twin Oaks is torn apart. But on the frontier, justice is never guaranteed. Packed with gunfights and classic Western action, THE FAST GUNS is the tenth book in the Fast Guns series by Terence Newnes.
