After taking down the man responsible for his best friend's death, Stuart Ramey is targeted by the killer's rogue artificial intelligence program known as Frigg and must enlist his fellow cyber security colleagues at High Noon Enterprises.

After taking down the man responsible for his best friend's death, Stuart Ramey thinks the case is finally closed. Then Stu finds himself left with a multimillion dollar fortune in Bitcoin in a desperate bid by Frigg, a rogue A.I. program created by the killer, to keep itself from being fully deactivated. To sort out his situation and take Frigg down for good, Stu enlists the help of Ali Reynolds and the rest of his cyber security colleagues at High Noon Enterprises. But they are not the only ones who know about Frigg's existence. Graciella Miramar, an unassuming accountant to all appearances, is actually the right-hand woman to El Pescado, the leader of a dangerous drug cartel. She'll do anything to get her hands on that program; she plans to take over her father's criminal underworld and become wealthy beyond her wildest dreams.
