Jessie Archer is a member of the Athena Protocol, an elite organization of female spies who enact vigilante justice around the world. Athena operatives are never supposed to shoot to kill--so when Jessie can't stop herself from pulling the trigger, she gets kicked out of the organization, right before a huge mission to take down a human trafficker in Belgrade. Jessie needs to right her wrong and prove herself, so she starts her own investigation into the trafficking. But going rogue means she has no one to watch her back as she delves into the horrors she uncovers. Meanwhile, her former teammates have been ordered to bring her down. Jessie must face danger from all sides if she's to complete her mission--and survive.
