According to @shalym, there is no DRM:

There were a couple of files that were not able to transfer. The error given was that the filename was too long. (This is using Win 8.1) Those files being missing didn't affect the functioning of the book, at least not as far as I could tell. Hyphenation still works, and the enhanced spacing at larger font sizes works too. I can't judge the kerning and other stuff, as I really can't see that.

If the book works on two different devices, it cannot be DRMed (I suppose Amazon *could* have moved backwards to per-account keys), so I am going to assume quiris' "unreadable blobs" are just the "new format we don't understand yet" part.

Thanks for all the pessimism.



EDIT2: s/encrypted/DRMed/g because of nitpicking.
