Cousins Justin and Adam are ecstatic about accompanying their aunt to Egypt. Both love adventure and know the work of James Kinnaird, an archaeologist searching for the tomb of an ancient Egyptian ruler, the Scarab King. Some dismiss the tomb as legend, but Justin and Adam believe differently.
From the moment their plane lands, Justin and Adam bounce from one mysterious event to another, starting from the moment a street peddler gives Adam an ancient scarab. Dr. Khalid, head of the department of antiquities and research at the Egyptian Museum, shows excessive interest in the cousins and their relic. Then, when the boys learn that James Kinnaird is missing, they realize something sinister is afoot.
Kidnapped and taken across the desert, the boys are plunged into serious danger and chased by ruthless enemies. Dr. Khalid will stop at nothing to discover the Scarab King's tomb and claim its treasures. But he has underestimated the boys' ingenuity.
Join Justin and Adam as they evade their captors and unravel the secrets of the Scarab King. Relying on their wits, courage, and each other, the boys must solve the mystery of the sacred scarab and rescue James Kinnaird before time runs out.
