Just got a new tablet and I'm quite new to this tablet world thing. Question. My wife emailed me a book that she had in her iPad. I received it and was able to open it. When it opens it opens using Amazon Kindle. But when I exit Amazon Kindle and close the email it's not showing on the Kindle library. I have to open it through email again. Meaning I have to make sure I don't erase that email. How can I save the book so it will open directly through Kindle and not using it through the email? Any help will be appreciated. Thanks.
