1.5 books a month is probably higher than the national average, but you'd be surprised how voracious a lot of readers are. I probably read 2 books a week, and I'm by no means a power reader by the standards of those who really are. I know quite a few people who regularly plow through 5 a week. Especially fiction readers and readers of "snackable" nonfiction (Jon Krakauer, Malcolm Gladwell, Michael Lewis, etc.).

Power readers are probably a small niche, but they're also a profitable niche. Younger readers (13-16), especially female, tend to consume YA novels like we consume HN posts. Vast fortunes have been made catering to that segment.
