Risk everything . . . for love with this #1 New York Times bestseller.

What if you couldn't touch anything in the outside world? Never breathe in the fresh air, feel the sun warm your face . . . or kiss the boy next door? In Everything, Everything, Maddy is a girl who's literally allergic to the outside world, and Olly is the boy who moves in next door . . . and becomes the greatest risk she's ever taken.

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.

Everything, Everything will make you laugh, cry, and feel everything in between. It's an innovative, inspiring, and heartbreakingly romantic debut novel that unfolds via vignettes, diary entries, illustrations, and more.
