I really enjoyed this novella. I read this after I read Partials and I feel like this helped me understand better what happened during the Isolation War and why the Partials turned against the humans. I liked Heron and found her to be an interesting and complex character (I have to admit that I liked following her a bit more than I liked following Kira). I would recommend this book to those who liked the first book in the series. For those who haven't read any of the series yet, I would recommend reading this after you have read the first in the series.
