The Golden War Chronicles: The Beginning

In a hidden kingdom, a powerful king and wise queen are blessed with twin sons who have superhuman powers. Or is it a curse? For they were born through the use of the king's brother's magic. The same magic is used to create a second, evil set of twins, setting the stage for a future battle for the survival of the kingdom. After the dust has settled and buried the ruins, this kingdom is forgotten until a pyramid is discovered by archaeologist Elanna Matthews, who triggers the pyramid's magic and the renewal of the ancient battle.
