Thirteen-year-old Steven is gifted. When he is chosen by the Sun God to help fulfill an ancient prophecy, Steven's mundane life is transformed into a journey of adventure and risk. Destined to eliminate the Guardians placed around the world by the Ruler of Darkness, Steven is immensely relieved that he has survived the first dangerous quest into the tomb of Seti I in the Valley of the Kings. But Steven has idea that during his next mission he will be tested by challenges thirteen-year-old boy has ever survived. Steven's next quest takes him once again through the portal in his father's laboratory and into the pits of the terracotta warriors of Chinese Emperor Qin Shi Huang's burial site. Accompanied by an Egyptian priest, a Mau, and a dragon, Steven must search among several thousand warriors to find the Guardian responsible for wreaking havoc on mankind. Encumbered by obstacles designed to kill any intruder entering the tomb, Steven has just eight hours to find and release the Guardian from the Ruler's control and return home before his aunt finds him missing and discovers the perilous quests he has been forced to undertake. Steven must find a way to operate the portal at will, before he is trapped in a tomb with evil forces determined to do whatever it takes to end his quest forever.
