If you'd like, I can move the domain mapping and the Value Bundle that you are currently using for savingparadisethebook.wordpress.com over to mikebondbooks.wordpress.com. Could you please confirm if that's what you'd like to do?
Rather than deleting your savingparadisethebook.wordpress.com blog, I'd suggest leaving it as-is, with the announcement that the blog has moved, or to purchase a Site Redirect to send visitors to your new site. That would minimize the risk of people visiting savingparadisethebook.wordpress.com and finding a deleted blog error and not knowing where to go.
