A Large Regular lists books he re-reads.
Re-reading The Killer Angels occurred to me the other day. I will have to follow through.
I've started re-reading Patrick O'Brian's Aubrey-Maturin novels. [I know a consultant who has read them six times!]
Last year, I re-read The Wind in the Willows. It was as charming as ever. An old friend reads Treasure Island every year.
I plan to give Neil Gaiman's Neverwhere another look.
It is true that some books bring special pleasure with repeated reading.
