Pride and Prejudice follows Elizabeth Bennet and Fitzwilliam Darcy (generally referred to as Mr Darcy) falling in love but being hindered by (as you might have guessed) too much pride and too much prejudice. Elizabeth's mother believes that "a single man in possession of a great fortune must therefore be in want of a wife" but more than this Mrs Bennet would like to see her children into a secure marriage so she can stop worrying about them since once Mr Bennet dies none of his five children will inherit his fortune. 
 Mr Darcy and Elizabeth do not fall in love at first sight, in fact that both do not really like one another at first, the process of them getting together is slow and rather humourous at times. The pacing, for me at the very least, was slow but that is more due to Pride and Prejudice not being the type of book I would typically read. The novel has a great underlying message that one should never judge someone at first sight, the book shows how utterly wrong one may be at their first snap judgement of another.
