My monthly Millions post is up, on how reading a series (in my case, the Rabbit books by John Updike) is so much better when done in one fell swoop instead of a book at a time over several months (or years).
1. Reading a set of books like this keeps everything fresh. Nothing is missed. Vague remembrances to scenes in past books are still top-of-mind, making every allusion memorable. You also start to see patterns more readily. There’s no time taken trying to figure out where a character or an odd turn of phrase, or a symbol or reference to earlier foreshadowing first appeared. You know. You encountered it just a few days prior.
So, there you go.
