Document Not Found error is the response I get when trying to get the library Kindle book for the book The Spark. If book is unavailable please remove
Sorry you're experiencing problems! Unfortunately it's hard from our end to see what the problem is. I'm assuming you're referring to the book titled The Spark by Chris Downie. When I look at the screen it tells me that there are currently no copies available for download. But what it doesn't tell me is whether or not that is because you or someone else has that copy.
The link you sent over also doesn't work for me, but again it's hard to tell whether there's a problem at Amazon, or if the link includes info that's actually specific to your Kindle account and so unable to be viewed by anyone else.
If Amazon thinks you have it checked out you can actually check it back in early by going to your Amazon account details, under 'Manage my Kindle'. If you see the book listed there, try checking it in and then going to our download page again to see if it is available once more.
Hopefully this will solve the problem. Please let us know if you continue to have difficulties.
