I have books I reread just because it gives me great pleasure and others that I reread because the author’s prose is so dense with ideas that I have to revisit the words after letting them percolate for a while. And there are others that I reread because I can’t make sense of the words or plot. Finally, there is one book I have been trying to read for four years and am unable to get past page 34 without giving up or falling asleep.
