Harry Potter and Ender Wiggin
Lately, I have become very interested, I admit it, obsessed with Orson Scott Card's disturbing fictional tale of how the manipulated child Ender Wiggin, his friends, family, and fellow child soldiers saved and influenced our earth of the future. I keep reading these expansion-type novels in the Ender series which tell the story of "Ender's Game" from the perspective of another character. So far I have read "Ender's Exile" and Ender's Shadow" to answer questions in my mind that the first book in the series did not sufficiently explain. I hope one day to get to "Speaker of the Dead" which is supposed to be the second book in the Ender series, but I want to find out as much information as I can before I move on, and so I will first need to read "Shadow of the Hegemony." I hear tell that there is also an expansion novel that relates the story of Ender's parents' courtship and life before they had before children. It seems I will never finish all of these books, and actually I do not want to because I am having such a good time.
Similarly, the sometimes harsh and painful Harry Potter series is ripe for expansion. Although J.K. Rowling wrote seven books already (some of them especially thick for children's literature), I think relevant information is still missing from the Potter story.
I am not sure if Rowling purposely left an opening for future writing, but she did do "The Tales of Beetle the Bard" which explained a part of the plot from the seventh and last book "Harry Potter and the Deathly Hallows." There are many other stories she could tell her readers, such as Voldemort's first dark siege, Dumbledore's adventures as he secretly searched for horcruxes, the story of the sisters Lily and Petunia, the origins of the Potter family, and Hagrid's life and experiences. Some of the ideas mentioned above could be combined into one book.
It has been approximately twelve years since the first "Harry Potter" book was published in 1998, so anyone who began reading the books at the age of eight is now at least nineteen. The books can begin to call attention to more adult themes. As a matter of fact, the books have featured more detailed violence as characters grew older and evil began to explicitly challenge good.
People ask how a person my age (48) came to be interested in children's literature. The "Ender" and "Potter" novels are character driven. I did not start reading the "Potter" books until four years after they came out, and I would laugh and look down my nose at the silly adults who were interested in a children's book. I suppose it was curiosity that made me read the first book and once I started I was drawn in by all the down to earth characters, especially the little boy whose parents were murdered. I needed to find out what would happen to him.
It is probable J.K. Rowling already thought of all this and much, much more. Personally, I just want an explanation as to how Hagrid's father impregnated a giantess. It had to be magic or something like it.
