My sister Emma and I enjoy bathing, ice cream, and laughing together. But for the past few weeks, Emma has changed completely: she hardly leaves her room and suddenly starts crying. Mom and Dad are also very serious and talk more and more quietly about her. Now she is supposed to see a doctor for the mind, a psychologist! Can I catch it? And am I perhaps to blame for something? "Shadow Sister" looks at the mental illness of depression from the perspective of a sibling in simple sentences and beautiful illustrations. Siblings often suffer greatly from the changed family situation, develop feelings of guilt, or feel left alone with their fears and questions. This book addresses these fears and feelings and shows ways to cope with the burdensome situation for all family members. It is complemented by a section for children.
