The 17-year-old daughter of a millionaire Newmarket breeder, Milly has watched her odious older brother become a jockey, and pursue a career she knows should be hers. Forbidden to race because of a childhood accident and her mother's notions about unladylike behavior, Milly is still secretly determined to follow her dreams. Then Bobby Cameron strides into her life, and nothing is ever the same.

She accepts his offer to work for a year at Highwood, desperate to make a name for herself in racing, and for Bobby to see her as a woman.

Caught up in a world where unscrupulous horse owners and billionaire media moguls rub shoulders, and more, with oversexed racing widows and fiercely ambitious jockeys, Milly must discover if she has what it takes to be a winner, on the track, in the bedroom, and, ultimately, in the game of love.
