Best friends Rosie and Adam find an old book with blank pages that fill with handwriting before their eyes. Something about this magical book has the power to make people vanish, even from memory. The power lies in a poem - a spell. When Adam's older sister, Shelby, disappears, they struggle to retain their memories of her as they race against time to bring her back from the void, risking their own lives in the process.
