Lahontan Valley War (Terrence Corcoran 4) by Johnny Gunn
Many wars between white men and Indians on the frontier started with the abduction and abuse of young white girls by the Indians. What Terrence Corcoran rides into is the opposite. White ranchers have abducted young Indian girls and abused them. This time, they made a mistake and left one alive.
Corcoran discovers a cattle-rustling ring run by the Indian Agent, gets involved in the makings of an all-out Indian uprising, and fights with everyone involved. All this because he wanted to visit some old friends in Virginia City.
