I decided to a series reread and as I said in my updated review of book 1, I wish I hadn't.
I found this book and bought it before I started the reread, so basically I was stuck with it.
This is basically just book one. It's fills in some information they weren't giving to Calla, but now it has me thinking about plot holes. Specifically about their glamor.
Calla, after deciding to be a doormat, starts asking a lot of questions. Kade, Atlas, Gabe, and Lex, aren't answering them. They say it's because they don't want Calla to use information against them, they say she'll get answers in time, blah, blah, blah.
They could have given her the answers and just glamored her not to talk about it, but nope.
