This reminded me of Northern Lights/The Golden Compass (Bolvangar and the "Intercision") meets Hunger Games (girl against the world, dystopian trilogy). I liked the idea of the story a lot more than I liked the story itself; Eva and Addie didn't grab me, but I will keep reading because I want to know how Eva/Addie and Ryan/Devon work out their relationship(s). The worldbuilding, at least, was really interesting, although a little too District 13 at the end with the "foreigners."
