You can download the Kobo app to your Kindle Fire or Oasis. (Doesn't work on Paperwhite). Your Kobo books will be found in the Kobo app, not your Kindle Library. Here's how to get the app if you don't already have Google Play on your Kindle (you can get the GP app using these instructions so you can get other apps not available through the App Store, and then just get the Kobo app through GP.) Kindle Settings Search for "Install unknown apps" Select Silk Browser and allow it to download unknown apps. Open Silk Broswer Search for the following depending on if you're in the US or UK (if you're in another country, replace the country code in one of these links) kobo.com/au/en/p/apps kobo.com/us/en/p/apps kobo.com/uk/en/p/apps
Once installed, the Kobo icon will be added to your apps. Sign in with your Kobo account (or make one).
