Query: Dark and rich

Dickens' shortest novel is an attack on utilitarianism, the squelching power of schools and factories to eliminate joy from life among the rich and poor alike. (Dickens perhaps prefigures Orwell with his Coketown of horror.) While some of the business about labor unions is unsuccessful, the love/despair story of Louisa Gradgrind is superbly rendered. A very good novel for those unsure of themselves in life!
