I know a lot of people are all Team Warner after the first book in this series. I was not, he was the bad guy, and I just always saw him that way. This little 1.5 novella in the series gives you a better insight into Warner, and so I can see a little bit how after reading this you could maybe be Team Warner. This story picks up right after Juliette, Adam, and Kenji escaped from Warner and his army. Warner was left with a gunshot wound that he is now recovering from. We see in this story just how much Warner is NOT loved by his men. How quickly they would be happy to see him gone. His obsession with Juliette is followed, and we see just how obsessed with her he truly was. There is a reason behind his obsession that is in the story. And you get more detail into how Warner and his father's relationship is handled. So you do feel some sympathy and see maybe why he is the way he is.
Not a lot of course about Juliette, other than parts of the journal that she left behind is written out in the book. It is interesting to take a look at how it really was for her in the isolation of the prison/asylum type place she'd been held. So in a way it gave us a look into her as well.
A quick read about Warner, and a good bridging point I'm sure to reach to the 2nd book, which I still need to get and read, Unravel Me.
