This innovative, heartfelt debut novel tells the story of a girl who's literally allergic to the outside world. When a new family moves in next door, she begins a complicated romance that challenges everything she's ever known. My disease is as rare as it is famous. Basically I'm allergic to the world. I don't leave my house, have not left my house in 17 years. The only people I ever see are my mom and my nurse, Carla. But then one day, a moving truck arrives next door. I look out my window, and I see him. He's tall, lean, and wearing all black - black T-shirt, black jeans, black sneakers, and a black knit cap that covers his hair completely. He catches me looking and stares at me. I stare right back. His name is Olly. Maybe we can't predict the future, but we can predict some things. For example, I am certainly going to fall in love with Olly. It's almost certainly going to be a disaster.
