On the eve of her high school graduation, proper socialite Francesca “Frankie” Fairholm rebelled against her elitist and controlling family to pursue the dark lifestyle of a contract killer for the enigmatic Osiris Corporation. Years later, with her training complete, she believes she’s doomed to the life of a sociopathic lone gun until a botched hit brings two unlikely allies, her cousins Addison and Katharine.

Using Katharine’s etiquette school, Elegance, Inc., as a front, the trio weave through Frankie’s dark underworld, carrying out contracts, drinking too much wine, and trying not to get each other killed.

Trouble follows the team home when the death of the cruel Fairholm matriarch reveals more than they ever wanted to know about their family. As the funeral preparations play out, the trio begin to realize there is much more to their employer than meets the eye and their family connections run deeper than they ever imagined.
