Just wanted to share my backup plan for getting this book tonight. I was going to download the VPN service, TunnelBear, which has a free 7 day trial. I would use it to mask my IP address to be a UK address and then download the ebook from this website.
I would have tried it as soon as the clock struck midnight in the UK tonight and immediately shared my results with the people here if I succeeded but USPS' site just confirmed my UK book order is already out for delivery so I might not have to do this.
