Ex-naval captain Colin Lord has had his fill of hot-headed adventure. Now, he wants nothing more than to put his tragic past behind him and pursue his career as a London veterinarian. Heiress Lady Ariadne St. Aubyn is on the run. She wants nothing more than to get the last of a rare breed of racehorse safely away from her wastrel brother before he and every reward hunter in England can catch her. But when the fiery noblewoman kidnaps the dashing veterinarian to oversee the health of her equally temperamental stallion, both Colin and Ariadne find themselves caught up in a wild chase across Regency England in which love, passion — and the Fastest Horse in the World — are all part of the stakes.
