Frontier Men by J.P. Bowie
Daniel MacLeod is running for his life from a grizzly bear, and the only one between him and certain death is another enemy - a Shoshone warrior, Red Hawk. Only, Red Hawk doesn't fit in with any of Daniel's preconceived ideas of how 'redskins' should look and act. Born to a French trapper and Shoshone woman, and educated in Boston, Red Hawk's dream to live with his people has gone terribly wrong. Thrown together in a fight for survival, the two men find a mutual attraction, but in order to build a life together, they first have to overcome the dangerous animals that lurk in the wilderness - and not all of them are on four legs.
