Human Division is a TOR DRM free title.
It shows as not supported for blackberry, which customer service says indicates it is not downloadable.
But I put it in my preview, and it shows as EPUB (DRM Free) which I believe means it would be downloadable if I bought it.
Now I could have sworn this was not downloadable when I initially looked, so I went to
ebooks.com and bought it as DRM free epub.
This example appears to show a TOR book from May 2013 as downloadable, but a TOR book from Aug 2014 as not downloadable.
So not all TOR books are impacted.
Next step is to look at the epub authoring.
