Category(ies): Literary speculation
This is an odd one. It appears between the publication of the 6th and the 7th Harry Potter books, and is a fairly serious attempt to work out what may occur in that final Harry Potter novel, based on what has appeared in the preceding six, and on public comments by JK Rowling herself.
As such, it will necessarily have a fairly short life, since the seventh book will be definitive, compared to the speculation herein.
And yet, and yet.
It does actually work quite well, because Langford has done an extremely good job of showing why certain things are likely to happen (and others not) within the logical construction of Rowling's world. He uses the existing works to demonstrate how she foreshadows future appearances, and how she skilfully misdirects readers by planting clues right in front of them while apparently showing them something else. As such, it's quite possible that this book can be republished with relatively few modifications after book 7 has appeared, as an explanation of how the entire sequence works as a single consistent story.
One for the Harry Potter fans, but providing more than just fanboy speculation.
