When Trouble Comes — L.A. Moore

With nothing but his horse and his Colt, Jack Applewhite is on the run from a posse in untamed Kansas. When he encounters two bounty hunters, Jack discovers his brother has been murdered and vows to avenge his death.

But avenging Thomas' death won't be easy. Jack has to make his way to Paradise City, Nebraska, ahead of those bounty hunters and find his brother's killer before the posse or the U.S. Marshal catch up to him.

Trouble is, the man Jack intends to kill is innocent.
