The Declaration and The Resistance by Gemma Malley

Well, this is about the two books (so far) in this series (I suppose) by Gemma Malley, and a small section of the second one, The Resistance, that confuses and annoys me.
**WARNING - SPOILERS AHEAD!**

For those who don't know these books:

The Declaration
A girl called Anna lives in the year 2140. Her actual name is Surplus Anna, as by now scientists have invented a drug that allows them to live forever. As a consequence, laws were passed only allowing people to have one child and then no children - because too many humans are too large a burden on Mother Nature. However desperate couples who have signed the Declaration (agreeing not to have children) still procreate. Their offspring are then Surpluses and, if found, face a grim fate. If they're lucky, they will be put into Surplus Halls and be trained to be Useful (slaves) and also to hate their parents for having them and being a burden on mother nature. Anna is such a child - until a Pending called Peter arrives and questions Longevity and all the things they are taught. She hates that she is drawn to him, but she is.

The Resistance
Continues the story of Anna and Peter. I suppose if you've read this far, you will be prepared for spoilers so here goes. After escaping from Grange Hall, Anna and Peter manage to rejoin Anna's parents. Unfortunately, the Catchers catch up with them soon after so Anna's parents kill themselves to allow Anna and her little brother Ben to live as Legals. Peter's mother killed Peter's father so that he could be Legal, and the Resistance tells the story of what happens after Peter - who has joined the Underground movement - gets an inside job at his grandfather's factory/lab, Pincent Pharma, which makes the Longevity drugs. Oooh!

Anyway, onto the point I wanted to make.
In the Resistance, Peter and Anna are set against signing the Declaration as they want to have children and create the Next Generation. Unfortunately, Peter's grandfather needs him to sign his Declaration for publicity purposes, so visits Anna to try to convince her to sign so that she won't be "holding Peter back". Anna then responds something like "but I can't Opt Out, I can't."
Opting Out is when you don't sign the Declaration, and all through this book this is what Anna wants, but in this one section she ... well you get the idea.

Has anyone else spotted this? Is it a typo or am I missing something?
Help much appreciated ~*X*~
