Being Metafilter, they've recommended all the books I can think of already. The first thing that came to mind was the Book of the New Sun (and the Long Sun and Short Sun books), since they were among the only books I read, then immediately started rereading, even knowing it would take me months to do it. While they were enjoyable on a surface level read, it was clear there was a lot I had missed. Huge understatement: 20 years later and I'm still rereading them every couple years (including right now). This makes me wonder if there is an effective upper boundary on how many pages a perfect bound, paperback (presumably roughly mass market size) can have before it's not feasible to read it. And what happens to those books after the prisoner finishes them: do they get added to the library, or disposed of?
