The first reading is for the plot. Every reading after that is for everything else, which is where most of the book was hiding.
We treat rereading as a luxury, or worse as a failure to keep up. The unread stack glares. But the number of books you can read in a life is fixed and small, and spending some of that number on the same book twice is not a waste. It is the only way to read a book completely.
What comes back different
You notice structure. The joins, the setups planted two hundred pages early, the scene quietly doing three jobs at once.
You notice the writing, because you are no longer being pulled forward by wanting to know.
And you notice yourself, which is the strange part. The passages you underlined at twenty are rarely the ones that stop you at thirty-five, and the gap between them is the most accurate diary you will ever keep.
A book you have read once is a book you have been told about.
How to choose
Reread the one you cannot summarise. If you loved a book and can only produce a vague shape of it, that is the one.
Do not reread out of duty. The point is pleasure, and duty is what turned most people off books in the first place.
Give it a year
Long enough to forget the sentences, short enough to remember why it mattered. Then go back and find out which of you has changed.
