I have to be in the minority here or maybe I'm not a successful language learner, but when it comes to reading in my target language I find it hard to "knock off a book in a sitting or two". As a matter of fact, right now I'm about to start a 442-page book in English which I consider one of my native languages. To read that in one sitting looks like binge-reading to me. And even two sittings would be pretty good.
As for reading a 200-page book in Spanish all in one or two sittings, we would have to talk about what reading means. But that's a whole other debate.
