thanks for the reply.
I see now that my message wasn't crystal clear.
I am after a
RSVP (rapid serial visual presentation) reader for iOS that handles ebooks.
From my research, all RSVP apps except Fastr Pro can only be used for reading articles online.
I can't download Bluefire at the moment. I am on a shared 256kbs satellite connection. I will have marginally faster internet (512) in a few days time.
I did load one of the epubs that didn't work in Fastr Pro, into iBooks, and the TOC works normally.
If I load an epub that was originally produced in that format, it works fine. I am able to tap on TOC links and it takes me to that location in the book. If I load an ePub that has been converted from mobi for example, tapping on the TOC does nothing.
