What would you want to see as one of the main subjects of an "absolute beginner's book on the Bible"?

I was shopping online for some Web design books and the search produced as part of the assemblage of books ”Absolute Beginner’s Guide to the Bible”. That got me thinking if someone dared to buy a book such as this to investigate the Bible, what one point, issue, etc. about the Bible they would hope the book addressed; things that are of the Bible, not the history, the method, etc.? Basically, ”I hope the book would explain blank to me.”
