This is the story of Cassandra, a member of a 'family' of assassins known as the Seven Sisters. They are elite. Skilled. Deadly. And Cassy is their strongest member. And yet she can't help but imagine what her life would've been like if she'd grown up in her first family - as Ally, a bubbling blonde toddler whose life was ripped away from her. She remembers a world where she isn't required to maim and kill others to survive. And then Cassy is given a choice - one she never thought she'd have: complete one last job, and leave the life she has been forced to endure for years. Leave behind her adoptive family, her first love, and her home, in exchange for the life she could have had. She must choose between a family that she has not known since her childhood and one that has raised her with a loving hand to do terrible things. And the task she has been assigned to guarantee her freedom is not an easy one. This is Cassy's story - one of self discovery, lost love, and gunfire.
