Maddy is allergic to the world; stepping outside the sterile sanctuary of her home could kill her. But then Olly moves in next door.

And just like that, Maddy realizes there's more to life than just being alive. You only get one chance at first love. And Maddy is ready to risk everything, everything to see where it leads.
