A book series written by J.K. Rowling. Though often compared to other works, like Tolkien's Lord of the Rings, Harry Potter has a different feel and message. Those of us who grew up with the series will have felt, albeit unconsciously, how the story and characters realistically evolve with time, with the theme, mood, and characters growing more mature with every novel, essentially getting older WITH the reader. Its subtle messages about the importance of love, the unimportance of death, and the similarities between good and evil are often missed by even devout readers, but have no less an impact.
Harry Potter is a success due to J.K. Rowling's skill as a novelist. On the other hand, Twilight's success mainly comes from indulging it's primarily female audience's desire to be ravaged by a big, strong, powerful man. This may sound sexist, but some women do feel this way, however since the rise of feminism society generally frowns upon women expressing such feelings. As such, authors are generally discouraged from doing this. This created a need in the market that unfortunately Stephanie Myer realized she could fill. Though she could be complimented for being a skilled economist (or for just being lucky) she should not, and hopefully will NEVER be acknowledged as a good, or even as a mediocre, writer.
