I have just started re-reading the Harry Potter series by way of reading it to my youngest child. In doing so, I've been reminded of how fascinated I was by how Rowling's writing pulls the reader in and holds them there. On the surface, it does not appear especially well written or cleverly constructed by the standard of other published and bestselling authors. Yet, clearly, it speaks powerfully to a vast number of readers, myself included.
Trying to elucidate why is beyond the scope of a Q & A site like this. However, I hope that asking whether or not any academics have tried to analyse the literary qualities success of the series might not be.
I am particularly interested in understanding how the writing is structured to maximise engagement with the reader. Take Harry's encounter with Ollivander, for example. The writing is simple, the sentences short. There is little description or dialogue. Yet Ollivander nevertheless emerges well sketched as a mysterious, vaguely sinister character and the lore of wands appears instantly fascinating.
That's just an example to illustrate what I'm seeking to learn more about: I have no especial interest in that passage alone. Can anyone point me at some academic discourse, ideally peer-reviewed, around this subject?
