Q: Itunes tells me my pre-ordered book is ready to download and never does...

So every time I download a new app from my iPhone 4s, a popup comes and tells me my pre-ordered book 'such wicked intent' is ready for download, and then asks if I'd like to download it now. So I always tap 'yes'.

However, no matter if I'm on 4g or my own internet at home, I always get a message that says "cannot connect to iTunes store, and the book never downloads.

What more is that when I search on the iTunese store from my computer, the book isn't in 'recently purchased' or anything, so it seems I can't download the book again with out REpaying for it.

How can this be fixed?
