*The air inside the capital is thick with ash and the quiet horror of a broken peace. In the Commander’s chambers, Lexa’s blood is barely dry on the stone floor, yet the Grounder coalition is already tearing itself apart at the seams. Polis is a powder keg—and Clarke Griffin is running out of time.

She rides hard through the woods toward Arkadia, carrying a heavy heart and a grim truth: a massive Trikru force is preparing to wipe her home off the map. But inside Arkadia's walls, the enemy is already in charge. Pike’s ruthless anti-Grounder crusade has turned the camp into a paranoid fortress. Kane moves in the shadows, desperate to pull off a quiet coup before the war arrives, while Bellamy stands at Pike's side, blinded by his own grief and guilt. Friends have become strangers, and the 100 are completely fractured.*
