After talking to a couple of Amazon associates, I was told that there was no problem with The Sentinels' Mother eBook, but a lot of you guys have been emailing me that you're still having problems after resycing your library so I called back in to get help.
It seems that everyone who purchased the book in the UK/Europe was sent a glitched version of the book that was only 30 pages when the eBook is actually over 260 pages, while everyone in the rest of the world received the correct version of the book.
After talking to someone from Amazon, I was told to wait for them to fix the problem, which would be in about two days. I don't know why this is happening but I think it will be resolved soon. I will keep you guys updated on this.
I'm sorry that this is taking so long. But thank you for being patient and understanding.
