The Instant #1 New York Times Bestseller If you love Eleanor and Park, Hazel and Augustus, and Mia and Adam, you'll love the story of Maddy, a girl who's literally allergic to the outside world, and Olly, the boy who moves in next door . . . and becomes the greatest risk she's ever taken. This innovative and heartfelt debut novel unfolds via vignettes, diary entries, illustrations, and more.   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 seventeen 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.
