Twelve-year-old Aaron Thompson had always been an only child.
However, after a freak attack, he is then led to a camp. He soon finds out he has two brothers. On top of that, he has to adjust to the life of a demigod.

Once Zeus finds out Poseidon had another kid, breaking the ancient oath of the Big Three never having children-again, he is determined to set things straight by offering a quest.
