Northanger Abbey, by Jane Austen
This book is not quite as interesting to me as Persuasion was, possibly because the main character is 17 instead of 28 like in Persuasion. She is flighty, like a normal 17 year old, but because I am more mature now, I disapproved of a lot of her choices of friends.
In the beginning of the book, we see her visiting Bath, England with a family friend. There, she engages in high society life, attending balls, dinner parties, and the theater. Eventually her time there ends and she is invited to the home of a friend, Elenor Tilney, where she engages in an embarrassing leap of the imagination, as teenage girls will sometimes do, and in an unrelated note, falls in love with Elenor's brother Henry. There is additional unrelated plot which, while tangent to the story, still adds dimension and interest. I did not care for this one as much as I did Persuasion, but it was still a good book.
I'd recommend this book only to Jane Austen fans, or perhaps to other 17-year-olds, or those who want to remember what it was like being a 17-year-old girl.
