Great romances - hmm.... difficult really.
Have you read Jane Eyre by Charlotte Bronte? I know it's a classic, but it really is worth reading. So is Pride and Prejudice by Jane Austen. Actually, all of her novels are marvellous. Then you could try reading some of the books by Christina Jones. They are light hearted and funny, romantic ideal for a cosy evening in. Try Love Potions for example by her.
