Extract ebook from an app
I'm new here and the recent owner of an iPad 3. iPhone user for many years but finally bit the bullet and purchased an iPad.
My problem. I bought an ebook from a publishers app. Folens (an Irish schoolbook company). Now, i'm of the belief that it's my book and I want the PDF file of this book from with this Bookreader app. I tried using Wondershare but it will only extract PDFs from iBooks purchased from the app store. I want to be able to view this book on my PC too when in the classroom (i'm a teacher and I don't have apple TV installed in my room). So, I paid €35 for this book but was of the belief I could use it as a PDF. The ebook is only viewable from within the Folens app.
Can anyone help me?
