As an imperfect Mexican daughter, I think I was hoping for more. This is a young adult coming of age story, the main character, Julia, is difficult, moody, a teenager. Her favorite book is Catcher in the Rye and I find the similarities between her and Holden Caulfield. In the same ways Catcher in the Rye annoyed me, Julia annoyed me. 
About halfway through the book she changes for the better, she matures and starts trying to look at things from others perspectives. I find myself liking this version of her much more. I see some pieces of me in Julia, which may not help me reconcile with myself, but may have helped a teenage me. 
The storyline about her sister personally felt anticlimactic and not what I had predicted but that doesn’t mean it was bad. 
Overall, the book was a page turner, I personally was just looking for more from these characters.
