Postlady Tracy Atkinson is ready to make sure Harry Potter fans get the weighty new book chronicling their hero's adventures.

In the real world, Tracy, from Witney, will have to do without the help of magic to transport copies of Harry Potter and the Order of the Phoenix to homes across Oxfordshire.

Extra vans are being laid on to move the 500,000 books being delivered nationwide -- including 7,000 in Oxfordshire -- because the book weighs 1kg and delivery staff can carry only 16kg of post in their bags.
