Opening Line: Harry Potter and the Philosopher's Stone by J.K. Rowling

So, a break from the usual choices of book: I put up a two-post series about critical terminology, mentioned J.K. Rowling by way of an example, and everybody abided by my request not to derail the discussion into a Harry Potter fan thread! Thank you all very much. By way of appreciation for anyone who had to restrain themselves, here: an Opening Line post on Harry Potter. Which is, in fact, an interesting subject. No slagging off Rowling as a person, please, we don't do that here, but I hope...
