Seductive, manipulative and a master of martial arts. Jade Dragon is the lead character of a chart topping videogame franchise. But someone in San Francisco is playing for real. The deadly game begins when a masked, leather-clad woman kidnaps Dragonsoft president Toshigi Tasoto, and delivers a ransom note to his daughter Nicole. In a daring move, she contacts the police, but they arrive too late to save her father. When more company employees fall prey to the unknown assassin – who themes her killings around famous Dragonsoft characters – it becomes clear Jade's vendetta has just started. Like the female ninja she imitates, the killer is an expert in combat, stealth and deception, as lethal with her bare hands as a samurai sword. On her bloody trail are veteran homicide Detective Lakeysia Symons and her young, womanizing partner Kyle Travis. Their investigations lead them to Nicole, who looks increasingly guilty as people connected to her continue to die. Kyle believes Nicole is a potential target whose life is in danger. But Lakeysia questions his judgment when he becomes intimately involved with the Japanese beauty. As their relationship heats up, so does the body count. Nowhere is safe. Jade Dragon strikes in her target's homes, their place of work, and even the police precinct. Nicole's past is the key to the mystery, but is she an innocent scapegoat... or a scheming killer about to complete her masterpiece?
