All I Need Is You by Johanna Lindsey
The headstrong child of Chandos Straton and Courteney Harte, Casey Straton inherited her mother's eyes and her father's stubborn temperament. Despite her prowess at roping, riding and shooting, the responsibility of running the family ranch is given to Casey's brother - so high-spirited Casey storms away from her Texas home, determined to prove to her family that she can do much more than "women's work". Damien Rutledge III, a successful New York businessman, has come west to kill the man who murdered his father. Despite his powerful physique and unwavering courage, his inability to handle a gun in this untamed country would have cost him his life if it weren't for the timely intervention of a youngster called "Kid". But there is more to Kid than meets the eye - for beneath the wide-brimmed hat and poncho is a stunningly sensuous woman - Casey Straton. The nearness of this handsome and fearless man awakens the fires of passion and touches her vulnerable heart, on the rocky trail that winds from dangerous duty to irrepressible love.
