The blood from yesterday's prison break is still fresh as armed collectors hunt the forty-two children who escaped into a city scarred by mankind's failings.

Separated from his fellow escapees and haunted by fragmented memories, Aiden battles to survive in the harsh streets. With only Daren by his side, blood on his hands, and a dangerous ally in Michael lurking within, he struggles to hold on to who he is—and what he's becoming.

In the heart of the Collective, Bishop William discovers Father Joshua has betrayed their holy mission, performing monstrous acts in God's name. As whispers of unholy power spread through Foundry, Bishop William faces the collapse of everything he's built and the fracturing of the Collective.

Meanwhile, Mira—stricken with a deadly illness presumed to be a mutation of Reaper's Breath—tracks down the collectors who took her son, unaware that an unseen predator is stalking her every move.

Survival. Secrets. The Collective's collapse. Nothing will ever be the same when their paths collide.
