I loved this book. I had just finished reading "Smile" and "Sisters" and then I decided to read this. As soon as I read the first page, I knew that I had made a good choice. This book is based on a family of four; a Mom and Dad, an elder sister and a younger sister. The younger sister has a type of sickness where she can't breathe very well where there is dust. And, every night, she has to put on a mask that keeps circulating air through her lungs. When they have to move, the parents don't want to, but it will be very beneficial for the whole family. Once they reach there, the elder sister makes new friends but doesn't want to be embarrassed by her sister. Don't worry, though. She takes her out when she has time. One day while exploring, they find an arcade. They go inside and find a boy. About the elder sister's age. Right from when they go in, the elder sister doesn't want the boy near her sister. Then, the boy shows them around. While going around, younger sister goes somewhere else while the elder sister is looking around. Therefore, the older sister doesn't notice. When she finally finds her sister, she finds the boy with her and they are dancing around with ghosts. When the sister shouts to get her sister out of there, the ghosts turn into dust. When that happens, the little sisters sickness occurs. She needs oxygen quick! When she gets home, she puts her sister's oxygen mask on and tells her parents what had happened. She is so mad at they boy, that she yells at him and tells him to never come near her sister again. Near the end, they bond together because of a festival that is very special to many people that are from Mexico. It is a festival where they meet the spirits of the loved ones that they lost. The elder sister finally finds out that the boy is not a bad influence on a younger sister. She lets him be around her younger sister and they soon become best friends. All three of them. Because of the story, this book deserves that rating I gave it. A 5/5! Have a great time reading and enjoy.
