What would you do if you could unleash a plague with just a thought? Sarah Vinson seems like an average, well-mannered, high school student in Portland, Oregon with a perfectly ordinary life. She has two loving, supportive parents. She lives in a comfortable home. She’s a good student. Her boyfriend dotes on her. But Sarah is not average and she is not ordinary. Sarah never gets ill. She’s never missed a day from school. She has no idea what the flu feels like. No cold has ever made her sneeze. No spoiled food has ever upset her stomach. No germ can harm her. Because locked within her are frighteningly potent powers over disease. When dark corporate forces from the Seattle-based Penwall Corporation learn of her existence and her abilities, they utilize their formidable resources to unlock those secrets for their own gain. Kidnapped and isolated, Sarah seemingly has no one to turn to for help or escape. It is all up to her to stop the Penwall scientists from continuing their mercilessly cruel testing—even if it means that she must harness her abilities and use them as a weapon. Immunity is a thrilling, grotesque, medical horror novel for fans of classic King.
