In 2540AD, the Kingdom of Zaul is an inhospitable world controlled by Cybergon 'Protectors' and ruled by 'The Keeper'. Humans are 'Worker' slaves, eliminated without thought. Thank goodness this is just a computer game - or is it? For Matt, the Kingdom of Zaul becomes all too real when his computer jams and he is sucked into the game. Now he is trapped, hunted by the Protectors and hiding among the Workers to survive. Matt must use his knowledge of computers and technology to free the people of Zaul and return to his own world. Keeper of the Kingdom is a gripping tale of technology out of control.
