My cousin (age 90) has a two month old IPad. She uses it to read books in very large type. I would like to send her an unpublished book from my Mac Book Pro via the Internet - in sections if I have to. It has pictures. I do not have access to my cousin's IPad, nor do I have one. What format do I need to put the book in so that her IPad can read it? What apps does she need to read it? I am happy to purchase an app for her if I knew what it was and how to get it to her. Can you assist me to make this book transfer?
