Noble Outlaw by Braun, Matt

John Wesley Hardin's powderkeg temper earned him twelve bodies by age twenty―and a place at the top of the Texas MOST WANTED list. Now a happy husband and a father, he thinks his fighting days are over and done. Until he's ambushed by an angry loser in a local poker game…

Soon the law is on Wes's trail again, but this time he's got too much at stake. Hardin only wants peace―but he's willing to wage a one-man war to stay free.
