Harrison Stoke, the Duke of Guildford, has just hired the unknown son of Britain's best horse trainer, to develop the prospects for his new racing stable. There's something about Vic that Harrison can't place, but the boy is a marvel with horses, and Stoke Stables has seen nothing but success since his arrival.
Vic has a secret, one that he's finding hard to keep from the attentive duke. Too many aristocratic men thought they could take advantage of a horse trainer's daughter so Victoria O'Reilly began to dress like a boy for protection. She became Vic O'Reilly, and the plan had worked well until she was nearly raped by the son of her employer. Her father sent her to Stoke Manor, hoping his friend would keep her safe. But when her attacker unexpectedly arrives at Stoke Manor, Victoria is injured, and her true identity is revealed, changing everything.
Harrison tries to keep her safe from the danger that haunts her while struggling not to form an attraction. Victoria tries to focus on training the duke's steeplechase prospects, but finds herself constantly distracted by his presence, and the aristocratic world she is thrown into.
Through danger, friendship, understanding, and victory, they learn that they weren't just training horses for the chase, but had been chasing each other all along.
