My daughter is a huge Harry Potter fan and, as luck has it, we will be in London for the release of the book on July 16. In the US, many of the large book stores have midnight parties for the release of a new Harry Potter book, does anyone know if any bookstores in London are planning the same type of thing. Can anyone recommend a large bookstore in London so I can pre-order a copy? If it makes any difference, we're staying in Bloomsbury. Thanks!!
