'The Adventures Of Lupo The Royal Dog: The Secret Of Windsor Castle', will hit bookshelves in September, with three more stories and a range of merchandise to follow.
Considering the effect Kate has had on the high street (hello Russell & Bromley nude court shoes!) we're pretty damn sure these books will fly off the shelves.
A kangaroo rucksack the royal couple were seen toting with Prince George during the Royal Tour of New Zealand and Australia sold out in hours of the pictures hitting the internet after all.
