Oh wow, you went hard. I got through around 50 last year (which was way more than I'd planned, and not something I intend to try again), but only a few were over 400 pages, with maybe a dozen novellas.
Anything in the super-long range you read that you'd recommend? I'm always hesitant to pick up anything with a high page count b/c they often seem like they're long just to be long, and slow pacing and me don't mix.
