She must simply execute the targets they text her and live to bury the tale. But then she's tasked with terminating a fellow assassin and glimpses her own future in her colleague's fate. When she leaves flowers on the gravesite, someone notices. Agent knows he'll have his work cut out for him when he's recruited by MI5 onto operation Archive to piece together patterns in cold cases. Nothing could ever have prepared him for Neva... An assassin obsessed with hell, a fugitive tortured by the secrets of her past, a woman destined to unthread him.
