I’m not entirely sure how I felt about this one. The narrative voice was interesting, though it often seemed like the narrator was too mature for her age (even with the whole genius thing, she seemed to have way more insight than a 13 year old should have). I liked No’s character, and I wanted more about her backstory. We get a lot about her mom, but I wanted more of No herself. One thing the book did well was rounding out the secondary characters. Lou’s family dynamic was well done, and I liked her mom’s arc. That being said, I wish Lucas’s character had gotten some more attention. I would’ve really liked to know what a 17 year old boy with a devil-may-care attitude had in common with Lou who, let’s not forget, is only 13 and a genius. The age gap just struck me as weird. All in all, this was a quick and engaging read, but I’m not in a hurry to read anything else by this author.
