Help! I purchased the wonderful al gore book called 'our choice' direct from the apps store. All good. It is a separate app but I thought it would just be put into iBooks. Nope. So, I thought I'll just drag the app to IBooks. Not good as it seems to have made a group containing iBooks and the Our choice book and not simply added it as a book to iBooks. Ok, so I removed Our choice from the group, but still have a black icon with a very small image of iBooks. So, please, how do I a) fix the iBook app icon back to original and b) add Our choice to iBooks? I thought this would be simple.
