Meet Grace Adams- an ordinary wife and mother collecting the cake for her daughter's sixteenth birthday party. But look closer, and Grace's life is falling apart. Husband Ben is divorcing her. Daughter Lotte has banned her from the party. And she's just abandoned her car in traffic. Still, no one thinks twice about a menopausal 40-something with a e200 cake hiking desperately across London. But to ignore Grace today would be a mistake. Because Grace Adams is also carrying a secret. One that she's kept quiet until now. And one that everyone who gets in her way is about to discover. That secret? You're about to find out . . .
