Confused PLEASE HELP

This app is gear about reading the few books that come with it. I cannot get it to access any of my thousands of books already in my ipad2. I bought this to read to my sight impared relative. I also got it to read to when my eyes were tired.

Only get this if you want the 10 books that come with it.
