Addition
“It all counts.”
Grace Lisa Vandenburg counts everything - the letters in her name, the poppy seeds on her orange cake. She counts because numbers hold the world together. But when a chance encounter with Seamus turns her world upside down, Grace's meticulously ordered life starts to unravel.
