Now, Surrette is on the loose and is leaving a trail of victims in Montana as he lets Dave and Clete know that they can expect more of the same for their daughters.But the two lawmen, representing good in this tale, are more than prepared to battle back against the evil that lurks around every corner.Beware of Montana. — Celeste Williams
