In 30 BCE, Cleopatra and her husband, Marc Antony, lost their war against Octavian for control of the Egyptian Empire. However, Cleopatra knew Octavian was really after the mysterious item that was the source of all her wealth and influence, so she hid it before committing suicide. She left a series of devious clues behind for her children to find it, but they were lost to history…until now. In a breathless adventure that takes her across the globe, Charlie must fight for her life against ruthless enemies, match wits with Cleopatra, and solve the two-thousand-year-old mystery to prevent the most powerful treasure of the ancient world from falling into the wrong hands.
