I managed to accidentally set the furthest-read location of one of my Kindle books to half-way through the book when in reality I hadn’t even started reading it. To be honest, I think it happened as a result of a bug in the Kindle for Mac app, but that’s not the point of this post.

I found some instructions online explaining how to reset the furthest-read location:

1. Visit “Your Account” page on amazon.com.
2. Go to “Manage Your Kindle” under “Digital Content” section.
3. Scroll down to “Manage synchronization between devices. Learn more.” and select “Learn more.”
4. Select “Turn Synchronization off.”
5. Make sure all your device locations are at or before the location you want to set in the book.
6. On a device which has the book in the right location, delete the book (you should write down the current location, just in case).
7. On the same device, go to the archive and re-add the book.
8. Open the book up (it should be in the same location as before).
9. Then turn synchronization back on.
10. Hit the manual sync on the device.

Unfortunately, like some of the commenters, I couldn’t get it to work. I think I figured out the secret sauce, though. Starting at step 6, I think it’s important to perform these steps using the device that set the furthest-read location last. In other words, before you try these steps, when you go to synchronize your location a popup will come up asking you if you want to sync to the furthest location. That popup will give the device name of the device that set the furthest location. It’s that device that you need to use when performing these steps.

In my case, attempting to reset it from my iPad failed every time, but once I wised up and tried it from the Kindle for Mac app, it worked straight away.
