Series background & context
Amelia Swiss, better known as Millie, is a chocolatier with a stubborn streak and a sweet dream. After a messy divorce, she moves to Paris to open her own chocolate shop, betting on a city she loves and a future she’s choosing for herself.
Paris is romantic. A murder investigation is not.
The series begins with Bonbon Betrayal, when a food critic drops dead after sampling Millie’s salted caramel bonbons and suspicion swirls around her shop. Millie has to protect her reputation fast, so she starts asking questions, following crumbs, and learning who in her new circle is playing dirty.
These mysteries keep the tone cozy and food-forward: chocolate-making, Paris streets, neighborhood regulars, and the pressure of keeping a small business alive. The crimes tend to connect to taste, status, and the egos that show up when food becomes art.
Across the books, Millie builds a new life in layers. Friendships form, romance simmers, and her confidence grows as she proves she can handle both the business and the danger. Each mystery is its own case, but the emotional through-line is Millie claiming space in a city that doesn’t hand it to anyone.
Start with Bonbon Betrayal and read in order if you want Paris coziness with a side of sleuthing and plenty of chocolate.
