On a top secret mission, top spy Yelena Belova discovers something very familiar about her next target.

Yelena is used to the brutal, cutthroat world of the Red Room--the elite, mysterious spy-training facility that raised her. But when her handlers send her on a top secret mission to the US--what they call "the American Outpost"--she finds barely capable girls who can't even take a punch. Yelena doesn't make many friends, but the freedom Americans enjoy gives her a glimpse of what her life could be--if she could ever escape the Red Room.
Then her mission goes terribly wrong. Now she's on the run with an orphaned eight-year-old. It's a deadly road trip of self-discovery, as Yelena outruns her past and struggles to save a girl who reminds Yelena of her younger self--a girl whose shocking origin ties her fate inextricably to Yelena's.
