...or i could figure it out right now.

Because I JUST realized you could turn pages in the books. Which is apparently not required until the 4th person and associated word.
This is 100% my fault! I'm still trying to find a good way to show/turn pages that doesn't feel obtrusive; I had buttons originally, but they were kind of ugly. Then I put in "mouse over to see the corners flip", which is too subtle! You used to be able to click on the whole page to turn them, but I had to disable that to implement copying the book text. So it's still just clicking on the corners (very fiddly) or arrow keys/A+D, which works fine...but it's not at all obvious, as you say, that you can turn the pages.
Game UI is hard!

Hmmm, that's not a bad idea! I'll give it some thought, might go with something like that!
