L C Knights was an English literary critic, an authority on Shakespeare. He said a good novel, 'Makes me walk more in the world.'
J F Kermode, another Cambridge man, was a British literary critic best known for his work The Sense of an Ending: Studies in the Theory of Fiction. He judged a novel to be good if it was re-readable.
I am in the world of a good novel days after I have finished reading it.
A good book grabs you by the end of first page and doesn't let you go until you have finished the whole thing....and leaves you wanting more.
The ones where I go to drink my cup of tea, and find it's gone cold.
