The story of two women with brutal pasts, addicted to each other but now trying desperately to live their lives without their drug of choice. For Villanelle, the assassin without a job, Eve is dead. For Eve, the ex-MI6 operative hiding in plain sight, Villanelle will never find her. All seems fine until a shocking and personal death sets them on a collision course yet again. The journey back to each other will cost both of them friends, family, and allegiances…and perhaps a share of their souls.
