98012 and the Guardian's Key (The Aretian Chronicles)

What would you do if you discovered your whole world was made up of lies? In the distant future, society commits to a more peaceful existence. Conformity is the rule. One night, Marcus 98012 awakens from a dream and is led to the horrifying truth. He discovers that nothing is what it seems as the unexplainable things around him come into focus: the mysterious elders, the disappearances of students- the oddly different Leila 98001. During Marcus’s search for the truth, he becomes a threat to the elders that run this mysterious world and he must decide between trying to destroy the system or escaping it with his life.
