Mia's not your typical hospital patient. Her next door neighbor Zac can hear her fighting with her mom and the nurses through their shared wall and he wishes she'd get over herself. But soon they are trading messages that evolve into a bond neither sees coming.

Apart from illness, they have little in common: she's a gorgeous girl with an entourage of perfect friends and he's a soccer-playing farm boy. In the real world, these two seventeen year-olds would have little to say to each other, but in the hospital the usual rules no longer apply.

By the time Zac is discharged, Mia is gone too, and he wonders about her. Is she okay? Is she better? He can't find out. She's left Facebook and won't answer his texts. Until the night he hears a tap at his window.

Told in alternating perspectives, Zac and Mia tracks the relationship of two ordinary teenagers in exceptional circumstances. They're both in remission, but cancer has changed everything, and normal isn't normal anymore. This is a funny and tender novel about hope, love, and courage.
