I know this wont stop that individual revealing the "code" to someone else, but just another layer in te jigsaw which would hopefully prevent them from disclosing.
I don't know if this will help but about 20 years ago in the days of MSDOS, at about the time PGP raised the neck hairs in the Intelligence Community, there was a product that decrypted a file one block at a time, cleared memory, re-encrypted it and decrypted the next block. That might do what you want but I don't know of a currently available product that does this but someone else might.

There is no eBook reader than could render a file encrypted this way and I doubt it would work right with ePub format on a computer either.
