Spoiled, sheltered Lady Sabrina refuses to wed Viscount Brisbane, betrothed to her by her parents. She has never met Brisbane and will not give up her knight, Sir Roderick, her father's factotum. They have secretly been in love for years. He is not of her class, however, and it can never be. She runs away to widowed cousin Lady Caldwell's country home, where Sabrina meets Brisbane and likes, maybe loves, him too. Lady Caldwell has a guest, a lecherous duke, who lusts after the fair Sabrina and vows to force her to wed him. Her cousin sweeps Sabrina out of the reach of the three men and into the whirl of a London season. The duke follows. Brisbane and Sir Roderick follow. Will her knight and her betrothed be able to win the battle against an influential duke and convince Sabrina she can have it all?
