One of the strongest points of this book are its characters. They are fleshed out and relatable, because they thought, acted and behaved like teenagers. Not only does the author incorporate diversity in ethnicities but also in sexualities with gives this book a very comtemporary twist (along with all of the magic and fantasy elements) to a Mexican tradition such as Dia de Muertos. 

It was so hard for me to get into this book in the beginning since it was a constant state of worldbuilding and setting bases for the story to be finally in motion. But when it did, it was hard to not listen to it. 
I found myself wanting more of certain parts of the story and less of others, but it was a good narrative overall.
