Hetty is one brave character. When a group of girls start having episodes where their body's start to disfigure. They are told to wait and someone will come to help them, but when Hetty's best friend disappears, she and her friend Reese hose out looking for her. Together they uncover the ugly truth about why their body's are going threw horrible episodes, and the fight for their life begins. Some experience are different. They call it the tox. I loved the characters Hetty, Reese. What they went threw was horrible,but the fact that they were able to fight and learn to truth. I was feeling bad for Reese, but also rooting for her to forgive Hetty for what she had to do to save their lives......
