This collects issues #1-5 with art by Frank Espinosa and Toby Cypress, and includes an "Art of Killing Girl" section with unseen art from both of the book's illustrators.
From the publisher:
What if the Mafia had their own Secret Service? Sara doesn't remember her name. What she does know is that she traded away misery as a former prostitute and became a world-class killing machine. When a routine hit goes sour, Sara makes a shocking discovery: Suppressed memories, haunting her since childhood, are in fact TRUE! And her REAL family, presumed dead, may actually still be alive!
