Publisher's Synopsis
Ember and Nova race against the proverbial clock. Tobin's sacrifice may have bought them some extra time to find a way to defeat Tris once and for all - he might also have shown them the way to defeat her in his final act of defiance. Year's end is coming quickly, and only two lives remain that can stand between Tris and her deadly plans. Between Nova and Ember, they have the wits and the strength to stand against Tris, but will that be enough to defeat her? This is the eleventh installment in a 12-part serial thriller.
