All I Need is You (Straton Series) Unabridged edition

In the American Wild West the law is young, and men and women must make their own justice. Casey Stratton has left behind an unbearable situation at home and set off on her own, relying on her courage and inventiveness to survive where most women could not. Damien Rutledge III is a society man from New York, thrusting aside his life of refinement and sophistication in favor of a more basic need - revenge. Their two worlds collide as Casey and the eastern gentleman chase the same outlaws, and when passion flares Damien is torn between avenging his father's death, and his love for the fiery Casey.
