Seventeen-year-old Charlotte Navarro never asked to be anyone's hero. If you're a hero, your sister isn't supposed to hate you. And you're definitely not supposed to get hooked on Gramma's painkillers. Even so, Charlotte's sister's friend Mia looks at her like she's some sort of hero. As Charlotte starts taking pills more and more, she has to question how it could hurt herself and others, even Mia. Is it a harmless habit or a dangerous addiction?
