Marie Lu is an amazing character writer. I loved the discussions June and Day had in Prodigy. It made sense how their points of view differed because of how and where they grew up. I also enjoy how Lu goes into a more grey story instead of a clear black and white story. I will elaborate on this in the spoiler section.

I loved that after the idealisation of The Colonies it is just very much Last Stage Capitalism. It is not this ideal country Day thought it would be. Like Kaede said in some regards it might be better, in others, it's worse.

I found the Tess/Day romance was unnecessary. It made for a nice contrast with the June/Anden romance like these are the pairings that might seem more obvious on first sight than June/Day but I liked how the relationship between Day and Tess was more like siblings in the first book. The book could have done without it for me.

The ending really dropped a bombshell with Day's diagnosis. And I am so annoyed with him for not telling the truth to June. Because he probably thinks it's the best for her, and that she will get to be with a guy he thinks is a good match for her, not telling her takes away her choice and it just annoys me so much in romances in books.

As for the assassination plot of Elector Anden I loved how grey it was and how difficult the decisions were for both June and Day. They really had to go for the least obvious choice, especially Day, he just did it all on trust. But right now it seems to be the right choice and I wonder what Champion will be like. I wonder if Lu will let Day die or if there will be some miracle solution. I wonder if June will become Princeps or a Senator. And I feel like June will definitely figure out that Day is sick.
