There are Four Truths
Four Truths given by God and proclaimed by the priests. They are the foundation of all life inside and outside of the Spire. They keep everyone in their place as is proper before God.
Sharn doesn't care about Truths. He only cares about begging or stealing enough to survive. He knows the stories; how the world had collapsed and all of society had moved to the great Spires to survive. He knows that he will never rise up the levels. He knows the Truths will keep him where he is.
Everything changes when a desperate plan for food goes awry and Sharn is forced to fight for his life.
The head of the Spire Guard witnesses the fight and takes Sharn to the Insula-an exclusive school where young boys are trained to fight for sport. Within the Insula's confines, Sharn learns to fight, tries to learn balance, and discovers that the priests' Four Truths are mere fragments of a grander narrative. There are three further truths that have been hidden from everyone, and a remnant of people who believe that God doesn't just want people to stay in their place.
As he navigates conflicting loyalties and battles his own doubts, Sharn must decide where he truly belongs and whether he dares to embrace the profound revelations of the Further Truths
