Why can't I read my Kindle Book on my Kindle or Kindle reading app?
Some Kindle Books from your library (including many picture books, read-alongs, and graphic novels) aren't supported on certain Kindle devices or reading apps.
To see whether a Kindle Book is incompatible with your device or app, look for a Kindle restrictions link under "Formats" on the ebook's details page.
If you already chose the Kindle Book format for an ebook with Kindle restrictions, you can try the Read now in browser option on your Loans page (under ) instead. This option might only be available in your web browser, not the OverDrive app.
Note: If you set Kindle as your reading preference, select Having trouble? under the Kindle button to see the Read now in browser option.
Otherwise, you can return the ebook to the library so you can borrow and download it again in another format (like EPUB).
