You have to reread the surface amusements of plot, subject and mystery drop away, the deeper pleasures of prose and reflection stay. I must have read some favourite novels 30 times Natalia Ginzburg's Lessico Famigliare, PG Wodehouse's The Code of the Woosters, Thomas Mann's Buddenbrooks, Laura Ingalls Wilder's Little House in the Big Woods and Elmore Leonard's Rum Punch. The most memorable rereadings in my life have been of Proust, who I read when I was 16, 18, 30 and 40 every time a different novel. It used to be a big farce about duchesses; these days it's about how to make sense of the world around you. I don't think you can read Proust, only reread, making adjustments and corrections and changes in understanding as you go.
