Asher has returned. After a decade of relative peace, Sarai leads Zion West as Prime Servant. Asher commands its army against the growing threats of Zion East's burgeoning military as Renatus's power continues to grow. But when Renatus finds out Asher and Sarai's son has the same genetic disorder as his wounded prince, he kidnaps him for his LifeCell in an effort to resurrect his own son. As Sarai and The Defiance are ousted in a coup orchestrated by her father, Asher does everything in his power to save their son.

Meanwhile, Cephas and Jude face their own challenges as they embark on a dangerous trek across the ocean in an attempt to rearm The Defiance. But a new menace looms. Protocol has grown even more sinister, as has Renatus's latest ally: Legion's brother, Apex.

The Fall delves into a darker narrative, providing deeper insight into the characters and the origins of The Wall. It is a fast-paced, clean YA dystopia that is ideal for fans of Red Rising and The Hunger Games.
