This was actually assigned me in high school--but amazingly, unlike what is so often the case, I didn't hold it against it. I find this a heartbreaking book--but oh so well worth reading. It's been compared to Jane Austen in its focus on family dynamics, courtship and social satire, but unlike Austen this is really an anti-romance. Catherine Sloper is not cut out of the cloth of which romantic heroines are made. A "good" girl but plain, socially awkward, and none too bright--and her clever father can't forgive her for it. The heart of this book is the battle between father and daughter over a man wooing Catherine. And the hell of it, is her father is right about Morris Townsend, but so badly misjudges and mistreats his daughter that I couldn't quite root for him to succeed. Catherine does change through the course of the book, and some might read the last paragraphs as triumphant--but I found it a Pyrrhic victory.
I haven't (yet) gone on to read more of Henry James--I understand this is one of his more readable books--he's known in his later works for very ... er... complex sentences, but that's not the case here in this short novel that falls early in his output. The book was the basis for two films, The Heiress with Olivia de Haviland and Washington Square with Jenifer Jason Leigh. Both are worthy and faithful adaptations.
