Another great Harlequin read from one of their best authors, Jeanne Allan. The summary from the back tells it better than I can:
"The Ferris Ranch, in the San Luis Valley, Colorado:
Stacy Hamelton--Once a calf-roping tomboy, now a big-city banker. Falling in love with Greg Ferris was her first mistake; marrying him was her second.
Greg Ferris--Handsome. Easygoing. Impossible to rile. When he arrived in the valley he hadn't known one end of a horse from the other. But now, with Stacy's help, he's one of the most successful ranchers around.
Stacy Hamelton returns to ranching country to end her farce of a marriage. She figures it'll be simple--just ask Greg for a divorce and go her seperate way. She hasn't counted on Greg attaching an impossible condition to their divorce!"
