There's a new Harry Potter book coming out about SNAPE. No, its not another novel in the mythos (sorry to get you excited). THE GREAT SNAPE DEBATE will examine Severus Snape, the traitorous Hogwarts instructor (although I'm a firm believer he's not a traitor at all). The book is described as a "massive Snape evaluation and character dissection".
Available exclusively at Borders and Waldenbooks, date to be announced soon.
