The central character is Grace Chibwana, a young woman with an African father and European mother. Grace is a fighter, toughened by a history of abuse, prostitution and drug taking before she was rescued, rehabilitated and given commando-style training by a group of soldiers of fortune led by her supposedly dead father. Now she finds herself at the centre of a struggle to rescue her sister's eight year old son from a gang of people traffickers run by Thornton, a sadistic serial killer living in Las Vegas. Grace has an unusual ally, Chi, her imaginary friend from childhood but now her ‘second personality’ whose re-emergence was triggered by her use of LSD. Chi sees things Grace may fail to see. Between them they miss nothing and have developed a strong mutual trust. Together they have to find where the child has been taken before it is too late to save him. In this fast moving story of no holds barred, brutal action we see the sheer speed and intelligence of her decision making and her merciless treatment of her foes bringing results which would not be possible for a more conventional investigator.
