The most exciting thing that ever happened to Blanche and Rosanna Montague is when a great bear of a boy came to their house injured, hungry and in need of refuge. He left before the girls got a chance to speak with him and so they dream of adventure still. Blanche Montague, companion to the eccentric Lady Sabella, finds herself entangled with Gareth McQuhae, a fugitive Scot, the villainous Earl of Eriskay, and Mordaunt Ravenswood, a secret agent for Bonnie Prince Charlie.
