I tend not to read books with characters under the age of 17 because they can come across as being immature and annoying.
However that is not the case in this, both Day and June are really mature for 15, maybe it's their upbringing; life on the streets and growing up in a posher area and being a member of the Republic.
I'll admit it took me a while to get into the story--about the 20-25% mark--what with the dual POV and one hunting the other down but once they finally met and got to now each other I became quickly engrossed in their story.
I wasn't sure how to feel about June's brother, Metias, but the more I read and grew to know him through June's memories and his journal, the more I liked him and was sorry that he'd died. He seemed like a really great big brother.
Action, political corruption, dystopia, a bit of romance; it was everything I like in a book and I liked a lot of things about it. I'll certainly be keeping an eye out for the rest of the series
