A) The author is working on a Disney game called Twisted Wonderland. I imagine it's taking up a great deal of her time.
B) The magazine in which the chapters of BB are published gives her a limited amount of pages each month. They recently cut the number of pages she gets, so it forces her to release shorter chapters.
C) Life issues, the world imploding on itself, other things we don't know about her personal life.

Each chapter is getting shorter and shorter. Does anyone know why? Is the author sick or what?
