My daughter got a hold of my Kindle Fire, 1st Generation and changed something in the settings on my home screen. I can no longer view any book covers of the books from my home screen. In other words, the book covers are hidden even in my library. Do you know what she clicked on to change this and how I can change this back? I have my books in order to read, but I still want to be able to see which book I'm opening. Thank you!
