Right... KA says the thought-speak problem in the book 1 is because she hadn't worked out her "series bible" before writing, that is, the set of rules for how things work in the series. Afterwards, she decided to change a few of the rules laid out in book 1, but since she'd already had it published, she was stuck with a plot inconsistency. She said the moral was for other aspiring authors to always work out your "series bible" before writing.
