I enjoyed this book more than I anticipated. Cecilia is a young heiress who can only receive her fortune if she marries a man who will take her name. Considering the era this is almost insurmountable unless she marries "beneath" her.
The book begins with her still under age and her uncle her guardian has died. He appoints three guardians and she must live with one of the three until her majority, in less than a year. The guardians are caricatures of the family/title proud with insufficient income, miser (out Scrooges Scrooge) and young man of means who happens to be married to her childhood friend. She moves to London where you get to meet the charming dilettante, the dissipated noble, gossiping ladies, scheming family friend and money lenders (who are of course always Jews). This is the short list of characters.
Fanny Burney tends to give relatively short descriptions of characters and then let the dialogue do the rest of the work. Of course for this to be a romance you have to have small misunderstandings and missed communications that keep our heiress and her intended apart. It was at times breathless but Cecilia while being perfect and charming is not so perfect or charming that she isn't likable.
