Imagine you have a fourth dimensional alien fused inside you.

I finished Felix Yz by Lisa Bunker. When Felix Yz is three, he gets a fourth dimension alien stuck inside him because of a science experiment gone wrong. (teleportation if you want to know) Everyone calls the alien Zyx. In this book, it is a story all about the events leading up to the zero moment. The zero moments is when they will stop Felixes heart and they will remove Zyx. Then they will try to send a shock with 100,000,000,000 volts of electricity into him and his heart should start again.  There is only a one in five chances of him living.  This book is very suspenseful and it is super good. I would recommend this book to people who like science fiction books and people who like to read about people with disabilities. I would give this book five stars.  It is really good!
