One-time pads, while unbreakable when used correctly as an encryption scheme, are not particularly useful for DRM!
To be unbreakable, the reading device would have to be preprogramed with a set of pad keys, unique to each device, whose total size was at least equal to the total size of all the books you would ever read in the lifetime of that device.
