The cowboy was six feet of rugged maleness and animal magnetism...When Liz Caine agreed to be a pretend princess for a week's stay at Lord Peter Morris's Montana ranch, she didn't know what he looked like in tight jeans and a Stetson pulled down to shade his chocolate brown eyes from the blazing sun. Or that he was her supposed fiancé!Pete would do anything to keep his ranch—except marry a princess. But for a bride of convenience, the woman who stood before him looked soft and yielding in all the right places. His only hope was to turn on the cowboy charm until she hightailed it into the sunset. And that's when he made his first mistake: he kissed her....
