From the book flap:
The Friday society follows the stories of three intelligent and talented young women who work as assistants to powerful men: Cora, lab assistant; Michiko, combat instruction assistant; and Nellie, Magician's assistant. Their lives become inexorably intertwined after a chance meeting at a ball ends with the discovery of a murdered mystery man. It's up to these three, in their own charming but bold way, to solve the murder--and the crimes they believe may be connected to it--without calling too much attention to themselves. Of course, blending in has never been these ladies' strong suit, especially with so many eligible men around.
Told with Adrienne Kress's sharp wit and a great deal of irreverence, this Steampunk mystery introduces three unforgettable and very ladylike--well, relatively ladylike--heroines poised for more dangerous adventures.
Clearly, these three young women are ahead of their time. They're independent, smart, and resourceful--but they live in an era where women receive little credit for their work except for their looks and supporting roles.
