“It's only in books--actual printed books--that you can easily start and stop your reading, that you can preread and reread, and, these days, as the book itself suffers from a cluster of plagues, it seems only right to pause and assert that the books that ought to be rescued these days are not the books that require a "spoiler alert"--such books are already spoiled--but books that aren't spoiled even if you know what's going to happen, even if you peek at the end, even if you're reading them for a second, or fifth, or dozenth time.”
