With a Jon Klassen appeal, Steve Antony, a debut author-illustrator, is the one to watch.

A sudden gust of wind sets off a marvellous London adventure for the Queen, the Queen's men and one very special hat. So let's follow one determined, daredevil queen through the zoo, over Tower Bridge and up Big Ben... just where will that hat land?

A witty and stylish celebration of London, the Queen and the royal family's new baby.
