Kate storms into town on horseback when she first meets Anthony. She's not here to find a husband, though — she's here to find a husband for her little sister, Edwina. She immediately has mixed feelings about Anthony — she's drawn to him and yet she doesn't trust him, especially not with her little sister.
When Anthony begins courting Edwina, though, it gets harder for her to resist him and vice versa. She vows to allow Edwina to marry him, though, so her grandparents will help their family financially. Edwina, though, catches on to her sister's feelings for Anthony and refuses to go through with the wedding.
With the wedding called off, Kate and Anthony give in to their desires and spend one night of passion together, after which Kate tries to run away — well, ride away on her horse. But when she falls and is knocked unconscious, it's Anthony who finds and saves her. Realising he absolutely can't be without her, he proposes. Naturally, she says no at first, but eventually gives in and the two wed.
