2: Cinder wasn't planned to be (minor spoiler's) daughter until the sentence where it was revealed - I was just as surprised as Innocence.
3: Innocence's middle name is... revealed in book #5, and she hates it far more than she hates her first name.
4: Succession rules for the Council have no gender preference, although females tend to have stronger magic.
5: In the first draft of book #1, Innocence was 16 years old. She was aged up to 17 for a couple of reasons: a) so her younger sister could be 16 and hence a little more adult, and b) so she could be a little more believably independent over the course of the series. (She turns 18 between book #1 and book #2)
So, is there anything you wish you knew about the Innocence Cooper series? Ask below in the comments. You won't get major spoilers of future books out of me, though :)
