One hot summer day, stuck in traffic on her way to pick up the cake for her daughter's sixteenth birthday party, Grace Adams snaps. She doesn't scream or cry or curl into a ball. She abandons her car and walks away - not from her life, but towards it. Towards the daughter who banned her from the party, towards the husband divorcing her. Towards the terrible thing that has blown their family apart. An emotionally compelling, frank and funny, unputdownable novel.
