Kindle books acquired with the Library's OverDrive subscription will automatically be returned after the 7 or 14 loan period that you chose at checkout. If you want to return Kindle books early, please go to "Manage Your Kindle" on Amazon's website (link below). After you sign in with your Amazon account, you will see a list of all your Kindle books including Library and purchased titles. To the right of the titles you want to return, click on "Action" and then "Delete from library".
