The Fourth Level - Book Five - Son of Ra

After accepting an offer from Audric Zimmerman to participate in an underground race, Charlemagne takes the kids and his intern from Oxford University, Johnathan Southern, to the land of the Pharaohs in search of the Amulet of Ra, an ancient and mythical artefact that once belonged the kings of this realm. Charlemagne, having once sought the artefact on his own years ago, is pressured to return to the quest as others amass and seek to collect the fifty million dollars being offered by the unknown host of the underground race.

However, Charlemagne runs into friends and foes, and in his haste to recover the amulet, becomes reckless. The children assist Charlemagne to the best of their abilities, but great dangers lie in the desert, especially in the form of a terrible enemy - Islamic terrorists with a desire to destroy the amulet for all that it represents.

Will Charlemagne be able to locate the amulet before the others or will the artefact fall into the hands of those that intend to sell or destroy it? What hidden secrets and great perils await for them in Egypt...?
