Query: Everyone Must Read This Book

Harry Potter and the order of the phoenix is quite possibly J.K. Rowlings finest work yet I got the book at the Barns and Noble Promo party at midnight and finshid 45 hours later. I just could not stop reading it. When I got home I read for 12 hours straight! the book is wonderful all around. you get the classic harry potter adventure theme but this time there is more of an underlying plot that takes center stage in the end. People you think are doing one thing turn up to be doing quite the oppisite. and I think that adds a whole new level to Harry's magical world. I would definatly recomend this book to everyone.
