"Germaine Johnson doesn't need a lot of friends. She has her work and her Sudoku puzzles. Until, that is, an incident at the insurance company she works for leaves her jobless-and she realizes that there are very few job openings for recently laid-off senior mathematicians with no people skills. With some luck (read: bad luck) Germaine manages to secure a position at city hall answering calls on the Senior Citizens Helpline. But it turns out that the mayor herself has something else in mind for Germaine: a secret project involving the troublemakers at the senior citizens' center and their feud with the neighbouring golf club-which happens to be run by the rakish yet disgraced national Sudoku champion, Don Thomas. Don and the mayor want the centre closed down and Germaine wants to help-because it makes sense economically, and because she's succumbing to Don's charms. But things get complicated when she starts getting to know the "troublemakers," and they open her eyes to a life outside of numbers and boxes."
