Description
The law will always catch up with you…
Lobo Johnson was a gunman with a price on his head. He was a killer, but he drew the line at murder.
His victims were violent men, murderers and renegades.
He had been set upon his present path by the tragic circumstances that engulfed his youth, and he carved a lonely trail through the West.
But with a history like his, the law wanted Lobo as much as they wanted the men he slew.
Just when he thought things couldn’t get any worse, everything changes when he rides into Deer Creek in Kansas. As soon as he meets Beth Anders, he forgets his golden rule in a desperate attempt to save a girl in trouble.
But Beth’s troubles are all too reminiscent of Lobo’s own tragic past and it’s not long before things hit a bit too close to home.
Can Lobo put right the wrongs in Deer Creek, without putting himself in the hands of the hangman?
Or will his first attempt to do the right thing ultimately backfire and do more harm than good?
Will Lobo remain true to the Fast-Draw Law, or will he meet a tragic end?
