Cookbook ghostwriter Kelly Madigan has a dependable boyfriend, a supportive if eccentric family and a career built on making other people's recipes and public images look perfect. After her mother's death, Kelly finds a letter criticising the safe, predictable life she has chosen. Determined to prove she can take a risk, she accepts a secretive assignment in London. Her client is Natasha Spencer, an Oscar-winning actress and health enthusiast whose demanding behaviour makes the project far more difficult than expected. While developing recipes and managing Natasha's celebrity world, Kelly is pulled into professional rivalry, family tensions and romantic complications. The experience forces her to decide whether changing her surroundings is enough, or whether she must also become more honest about the life and relationships she truly wants.
