If someone had told me 10 years ago that I wouldn't start reading the Harry Potter series until 2009, & that I'd start doing so to divert myself from my father's loosing battle with cancer, I wouldn't have believed them. But that's what's going on, & it's working very well in the diversion category.
I don't know yet about the other books in the series, but I can say that J.K. Rowling tapped into something we all want--a unique, wonderful world where we truly "belong". Isn't that what we all want? A place where we are accepted as we are, & where our natural talents are celebrated, as opposed to ridiculed? It's pretty universal.
I know when I was little I used to imagine that I was an alien from another planet that was dropped off here by accident when I was born. That would explain my lack of fitting in, & why even though I tried really hard to please my family, it was never enough. I think we've all felt that way from time to time in our lives. Wouldn't it be neat if we could all just go off to Hogwarts for 9 months & "find ourselves"?
