Murder, Magic, and What We Wore (Carton of 12 Hardcover Books)

The year is 1818, the city is London, and 16-year-old Annis Whitworth has just learned that her father is dead and all his money is missing. And so, of course, she decides to become a spy.

Annis always suspected that her father was himself a spy, and following in his footsteps to unmask his killer makes perfect sense. Alas, it does not make sense to England's current spymasters—not even when Annis reveals that she has the rare magical ability to sew glamours: garments that can disguise the wearer completely.

Well, if the spies are too pigheaded to take on a young woman of quality, then Annis will take them on. And so she crafts a new double life for herself. Miss Annis Whitworth will appear to live a quiet life in a country cottage with her aunt, and Annis-in-disguise as Madame Martine, glamour artist, will open a magical dressmaking shop. That way she can earn a living, maintain her social standing, and, in her spare time, follow the coded clues her father left behind and unmask his killer.

It can't be any harder than navigating the London social season, can it?
