Each of the three books of this space opera triology has a different protagonist in the same universe. In this case the story focuses on Ryan Azarcon, a blond, blue eyed celebrity with famous parents.
This book seemed to start a little before Warchild ended, on a parallel storyline, and then continued where it left off. We meet characters in Warchild like Jos and Warboy, but they are secondary ones. Compared to Jos, I thought that Ryan was 'softer' than him, because he's been lucky enough to be kept apart from the horrors of war by his parents, but Ryan had other skills because of his fame. It was interesting to see Jos and his father through Ryan's eyes though - his upbringing taught him about reading others.
Overall: I recommend these books if you like well written world-building and character driven development. The writing is top-notch, and despite the background in space, it focusses on individuals. I really like the way the characters interacted, especially Ryan and his father and Sid. I wish Lowachee would write a book about how Cairo Azercon was adopted by his parents, I was curious about his background, though some of it was revealed throughout Burndive.
Good read.But be prepared for angst.
