The white space is for the bar code which will be inserted as soon as Create Space (who are going to print the book) accept the final version.
I hope you like it. It's a bit different but when self publishing you have to go with your gut instinct!
I am hoping to get the go ahead and go live before I head on my holidays this weekend, but will see what happens. Whatever happens it will be available to buy either in print or on Kindle before the month is out. Looking forward to hearing people's reactions to the book, hopefully they'll find it a laugh out loud good read!
