(That is what is called a rhetorical question. Please remove the book from your device and redownload it.” Apart from it being an utter waste of time to re-download every book (one by one), what if I had been somewhere with no internet service? And, “remove the book from your device and redownload”. Kindle app starts, shows me my library (every volume Downloaded), but any book I try to read in my library, Kindle says “Preparing your book”, followed by “The book could not be opened.
