Sigh. There is nothing worse than having my suspicions confirmed.
The place you got that book from, xBooks, is a pirate source where people go to steal books from iBooks/Apple. Shame on you for having and using it.
This forum does not condone piracy. Not only is piracy, and any discussion thereof, against the rules of this forum, it's theft and thus illegal.
You will receive no further help from this forum, except for this bit of advice: Remove that repo from your iPad, don't use xBooks and use the iBooks store the way honest people do - buy your books!
