I haven't ever used Google Books until today. I got a free book from the Play Store, I had to install Google Books in order to open it and read it. The app seems great, nice interface and everything. Now, I've been trying to figure out where these books are stored? I've searched everywhere but wasn't able to find an answer. I'd like to be able to read the books on my computer, ereader, etc. not just on my Nexus 7.
