This is a really thoughtful
character exploration. It's set before the events of [b:Unspoken|10866624|Unspoken (The Lynburn Legacy, #1)|Sarah Rees Brennan|http://d.gr-assets.com/books/1333397426s/10866624.jpg|15781826], following some of the same characters. We see them in their natural habitat, so to speak, before all hell breaks out in the main series.
(Ahahaha, not that all hell doesn't break out in this one. Kami, amirite?)
I'm not sure if this would work very well as a stand-alone piece, but oh it fits so elegant with Unspoken. I'm trying not to make this into a list of spoilers, so I just deleted the list of "things i loved". However, I think all of the things I love fall under the heading of how AWARE the author is of the nuances of people and tropes. Like how Kami's bad romance with a college guy doesn't go the "expected way," (and how I didn't realize I'd expected it until it didn't happen,) and how Kami and Angela wound each other when they see each other as Character Roles, and anything with Rusty.
To sum up: if you read this, you should read Unspoken as well. But you should always read Unspoken.
