Wuthering Heights is Emilly Bronte's only novel.
Wuthering Heights is the name of the Yorkshire farmhouse where the story unfolds. The book's core theme is the destructive effect of jealousy and vengefulness both on the jealous or vengeful individuals and on their communities.
Reading books is one of the best ways to improve your english language and also to introduce yourself english culture and to know all the things that mattered to the author of the book. One of my favourite books is this one, because it is controversial, and interesting, and full of tension, it just keeps you reading.
It is very interesting to me how Hareton Ernshaw changes his character through the book, and it is also enchanting to watch how Catherine changes him.
