While the details surrounding the popularity of Harry Potter can at times be sketchy - just how popular was the first book before the media got ahold of the story? - the fact is that author J. K. Rowling somehow managed to get a whole generation of kids totally hooked on a series of door stoppers each larger than the last (well, okay, the last two started to shrink a bit, but still). And all about some kid named Harry who finds out he's a wizard. So it's no surprise that people want to follow Rowling's success with successes of their own. The question is, How?
