I'm not sure if it'll work on the Aura due to the need for the kobotweaks plug-in, but there are two PDF reader programs with PDF reflow available in the Developer's Corner. They're in the KindlePDFReader thread. There is also another alternative available.

There is a "satisfactory"(really quite effective), but perhaps slightly ethically questionable method... One can visit Apprentice Alf, download the appropriate plug-in for Calibre to strip the protection while importing, convert the title to epub format and enjoy the book. Finish it, and delete it from reader and calibre prior to the end of your lending period and the ethical conundrum is minimized, if not wholly eliminated for most.

I think as long as you're deleting the text, it's probably fair to consider the rest of the process as simply translating it into a machine readable form compatible with your reader -though I'll be surprised if someone doesn't verbally impale me for this practical expedience. I will retort in advance that had Adobe any sense at all they could easily provide the conversion while keeping the DRM in effect as a function of ADE -though I suspect the DRM crowd would still collectively pass an example of rectangular three dimensional baked building material.
