After reading The Secret Countess by Eva Ibbotson, I moved onto another of her books, Magic Flutes. Again, this book has a lot of historical detail in it, but what made it charming was the description of how an opera is put together.
Like The Secret Countess, there was a similar plot. Heroine of high ranking somehow loses her fortune and must work in a lowly job. Guy (and in Magic Flutes, the guy is actually called Guy :D) of fairly high ranking is soon to be married to a woman who on the surface seems totally suitable, but is actually shallow. The guy meets the heroine, and falls in love with her. The fiancée is tricked into calling off the marriage, and the guy and girl is able to get married and live happily ever after.
I can’t fault the book though, as it’s well written, and is a pretty good story.
