From shot girl to assassin...

When eighteen-year-old Sky Malone left England to work for Emmy Black, she realised her new job wouldn't be easy. After all, being Superwoman's sidekick wasn't a career you could half-ass.

In Virginia, she finds every day is a battle. Against exhaustion, against her tall, dark, and grouchy mentor Rafael, and against the ghosts of her past.

And as if that isn't tough enough, after just two months, she's flung into the middle of an undercover operation that leaves her fighting not only for her place on the team but for her life as well.
