I'm looking for Kobo books that have Beyond The Book features enabled. Preferably one that's available for free and without DRM in Canada, but I'm open to taking a vacation to warmer and sunnier countries if necessary
I'm also willing to pay for such a book, but I have rather narrow interests in epic fantasy (and yet I have a massive TBR list!) and I'm not interested in paying more than I think is fair for a book (which of course varies depending on the author and the book and the square of the natual log of the cube of the number of arc seconds between Saturn and Io from a vantage point one-half AU above L3...

).
And the reason I'm here looking for books that have Beyond The Book enabled? Because Kobo, in their efforts to make their web site more useful to users, completely removed their format listings and decided not to note which books have Beyond The Book features!
