Books that Visitors take

[Azura_Zuzu]

I see on loading screens and some tooltips that some "untrustworthy" Visitors might just take books, and I'm unclear on how likely that is to happen... I've never had it happen spontaneously.

However, I do know that showing specific books to specific people (in particular, Hokobold and Arun Peel) may have them "buy" those books from me and leave with them. What I'd like to know is; the ones that they take this way, can they ever be reobtained? Or are they gone for good now?

To the best of my knowledge, they cannot be reobtained; this is specifically because of the way the book decks work, so burning the books or throwing them into the sea will also not let you get a book back.

Last I knew, though, any book you get from a "Secret of the House" can be obtained repeatedly if you get rid of it, because the game checks for the book when deciding if the recipe works, rather than pulling from a deck or having some other self-terminating variable.
