At first I was excited to get an ARC of this. But after 50 pages, I was too exasperated to continue. The writing style was juvenile, the romance was already overwhelming the story, and from what I can tell the plot mostly just consists of a boy running and Zoe following. Suspense is built by having well-placed Regulators whenever she starts to feel comfortable. The other thing that bugged me about this one was that Zoe is just another female MC who is actually drop dead gorgeous but she doesn't know it. Haven't we done that to death at this point?! 
 Another good idea gone wrong, in my opinion. If you want an X-Men dystopian, try Shatter Me by Mafi. Lots of heavy-handed romance there too, but far better writing style.
