Have been using Aldiko to read my epub books for awhile. However it does not let me open a book where I left off or sync settings to 2 tablets. I read that Google Play will do what I want. ( unless you can recommend something else?) But having problems importing books. What is the best way? I have about 100 I would like to add to start with. Is it possible to add them to my Google Drive then import that way? What is the easiest way?
