Everything has changed. The Dome is no longer the safe haven its residents believed. The districts are in the hands of the enemy. And Authority is stronger in every way, with more warriors, more resources, and more information. The rebellion continues. While there’s life, there’s hope, and those rebelling against Authority won’t give up. They’ll fight to the death. The dark glass will shatter, and the final target will fall.

Can old adversaries become allies? Rodin knows Authority must be stopped, and that means returning to the Dome. But the only one who knows a way in is Cat, the one-time Authority agent who has been manipulating Rodin for years, playing with Rodin's life for his own suspicious ends. To the south of the Dome, Authority relentlessly push Genna back, forcing a retreat into the heart of her district. Soon, she will be surrounded and outgunned. But there's one man who could help – the same man who once betrayed her, who was responsible for the near-destruction of her district, who stood by and watched as she was tortured close to death. With so many lives at stake, can Rodin and Genna do the unthinkable and work with their enemies?

They might have won the battle, but the war is only just starting. Rodin heads west, into a fractured district, on the verge of collapse unless he can pull disparate forces together, once more putting his life on the line.Cat, to the north, walks a tightrope deep within Authority, where those above him surely know of his betrayal, where he can trust nobody and nothing, where any wrong move may be his last.And behind it all Authority moves, bringing pieces into play, dividing their enemies, preparing for victory.
