More of a melodrama than a sprightly love story.
A young lady, only nearly a woman goes to London upon invitation by her aunt. As her family is poor, she is only able to go because her sister loans her dresses from when she had gone to her aunt some years before, the visit which was ended tragically when her husband to be died the week before their wedding.
In London, Theodora becomes her aunt’s favourite. She also becomes friendly with another favourite, Denis Ogilby. She learns Mr Ogilby has been engaged to Pricilla Gower. Theo makes Priscilla’s acquaintance. But the friendship with Denis grows, and, on his part, deepens. He realises he is in a dilemma and goes to the continent, admitting his cowardice. His absence makes her realise she has feelings, too. But she determines not to be the cause of him being dishonourable.
When Mrs Throckmorton decides she must go with Theodora to Paris, Theo becomes the fame of the season.
From there, fate moves swiftly; involving sacrifice, distress, and consternation to Denis, Pricilla and Theodora.
