It's come to me in a dream--the seventh book in the series will be Harry Potter and the Chef's Knife, detailing the adventures of Ron and Harry as they discover the secrets of Saint Theresa of Avila, who ate nothing but mayonnaise. Yes, I really did dream that, and would probably prefer to read such an absurdity than whatever J.K. Rowling comes up with next. After the Half-Blood Prince, I have no reason to read any further. All interest in the characters has been lost for me--I'm still extremely upset. I read the sixth book the day after it came out, and am just now getting around to posting about it, yet still I feel betrayed and apathetic at the same time. This may be a spoiler; I'm sorry.
