Nefertari "Terry" Hughes is looking forward to spending the school break with her boyfriend, but when her archaeologist father announces he's working on a project that will take him to Egypt, all hopes of having a romantic summer are buried. Terry accompanies her father to Alexandria where she's reunited with her first crush, Awad-all grown up and an expert in translating hieroglyphics. He confides that the team is in a race to find Cleopatra's lost tomb before a secret band of rebels steals Egypt's last Pharaoh and her diadem. But sabotage and a deadly accident put everyone on high alert, and Terry isn't sure whom to trust. As the line between ally and enemy begins to blur, Terry has to keep her wits about her and figure out who wants the diadem badly enough to kill.
