Seventeen-year-old Flora Banks has no short-term memory. Her mind resets itself several times a day, and has since the age of ten, when the tumor that was removed from Flora’s brain took with it her ability to make new memories. That is, until she kisses Drake, her best friend’s boyfriend, the night before he leaves town. Miraculously, this one memory breaks through Flora’s fractured mind, and sticks. Flora is convinced that Drake is responsible for restoring her memory and making her whole again. So when an encouraging email from Drake suggests she meet him on the other side of the world, Flora knows with certainty that this is the first step toward reclaiming her life. 
Born in a refugee camp, all Subhi knows of the world is that he’s at least 19 fence diamonds high, the nice Jackets never stay long, and at night he dreams that the sea finds its way to his tent, bringing with it unusual treasures.

Carrying a notebook that she’s unable to read and wearing a sparrow made out of bone around her neck – both talismans of her family’s past and the mother she’s lost – Jimmie strikes up an unlikely friendship with Subhi beyond the fence. As he reads aloud the tale of how Jimmie’s family came to be, both children discover the importance of their own stories in writing their futures.
