Harry's Death

Back in 2006 it was suspected that Harry would not survive in Volume 7
and no less than John Irving and Stephen King pleaded with JKR to let
Harry live. I think that originally Harry was supposed to die but JKR
bowed to pressure and changed the ending. It would explain a lot: the
weak epilog, the Harry's a horcrux/no he's not waffling, the weird
heavenly chapter, the strange conversion of Narcissa Malfoy, etc.
