So let's take a look at the ten most popular books, as decided by how many fanfics people have written for them:
- Harry Potter (612,223)
- Twilight (201,237)
- Lord of the Rings (46,801)
- Percy Jackson and the Olympians (30,096)
- Hunger Games (24,781)
- Maximum Ride (16,517)
- Warriors (13,627)
- Phantom of the Opera (10,424)
- Chronicles of Narnia (9,889)
- Gossip Girl (9,340)
Just looking at the list, it seems that the trend is towards fantasy books, as opposed to, I dunno, mystery novels. Poor Nancy Drew doesn't show up until #46 on the list. And the list seems to indicate that a series of books is more popular than just an individual book. I suppose that explains why every popular book or movie tends to get an automatic sequel.
Isn't Phantom of the Opera a play? As in, an actual opera? I remember taking a field trip to see it once, when I was in middle school. We decided that watching people sing in foreign languages wasn't our cup of tea.
