Colorado rancher Johanna Kellerman needs a horse trainer. She can't believe her good fortune when Cade Larrabee shows up. Cade has a way with horses ... and with women. Blackmailed by General Victor Wingate, his former commanding officer in the Union Army, to spy on Johanna, Cade struggles with his conscience and his growing feelings for her. It's just Cade Larrabee's luck to have to choose between the stipulations of the blackmail and deceive Johanna, or disregard the scheme, favoring his overwhelming attraction toward her. By abiding by the terms of the extortion, Cade protects his brother, but he could lose his newfound love.
Johanna discovers that Cade is not what he pretended to be, after both have developed sincere affection for each other. Can something that feels so right be brought together by something so wrong? Can she ever believe anything he tells her again?
