'Wuthering Heights' is one of the greatest love stories ever written because their love between Cathy and Heathcliffe is doomed never to make them happy together. The novel is complex in construction, following the story from the perspective of various characters within it. The underlying passion they feel for each other is the heart of the story, and against all odds and circumatnces, it consumes them both to the point of death, and beyond. Try reading the novel again, and concentrate on the aspects of the Cathy -Heathcliffe access, which ias actually the heart and narative thrust of the novel. Hope you enjoy it more next time round.
