JULY 18thPlease, keep the plot a secret! Don't spoil it for others who have been waiting years for answers.
We are almost there! As launch night looms, let's all, please, ignore the misinformation popping up on the web and in the press on the plot of Harry Potter and the Deathly Hallows. I'd like to ask everyone who calls themselves a Potter fan to help preserve the secrecy of the plot for all those who are looking forward to reading the book at the same time on publication day. In a very short time you will know EVERYTHING!
For HP fans, this month's "Wizard of the Month" is Godric Gryffindor!
