This book won't open. The sample worked fine but when I bought I tried to read the book I found it wouldn't open. I deleted and redownloaded the book but it didn't work. Eventually after trying for a long time it just gave me the message this book is not formatted for iBooks. I bought this thing on iBooks and it's not formated for iBooks. This is a scam. Apple take this off the app store and give me my money back.
