Sarah, Ella and Verity queued for their books in Milton Keynes. They couldn't wait to start reading and opened their books in the shop!
Jamie, 13, sent in this picture of the Potter queue in Brussels in Belgium.
Matthew, 10, and Jessica, 8, queued for ages in St Albans to get a copy of the book and already know who dies!
Even their cat Sammy couldn't wait to get his paws on a copy - but he wasn't too happy when he couldn't find a mention of Crookshanks straight away!!
