This is full of very useful information, and it's written in a clear and very easy-to-understand way. However, it doesn't go into a great amount of detail, I know brevity is the soul of wit and all but this book could be a little more in depth with the things it talks about. However, as an INTRODUCTION to studying the novel, this book is to be honest pretty good. You could certainly do a lot worse! But as a work explaining how to be a good reader it is functional but pretty sparse.
It's also unbelievably arid and dry, and structured bizarrely poorly. I don't really know Jeremy Hawthorn's work or reputation (I can't help but notice another reviewer on this site doesn't think much of him as a person, for no reason I could find after googling his name), but he doesn't settle a reader into a new idea as well as he could. The introduction to the fifth edition is very oddly written, seeming to suggest the reader should already be familiar with previous editions of this book - and then the introduction sets up a later chapter, jumping into a discussion about Structuralism and the difference between Synchronic readings and Diachronic readings of a text. This is then followed by the first chapter, which attempts to define the word 'novel' and the history of the novel as a concept. A better structure would help this book immensely - maybe this is fixed with more recent editions?
EDIT: I see the reviewer who called Jeremy Hawthorn a 'twat' had him respond to her review, which I find really funny!
