Every step has led to this … The Shining City. The last symbol of the old world’s cruelty. A fortress of power, privilege—and everything they’ve vowed to destroy. William, Matilda, and Olga came from Edin. Gracie from Dout. Rayne and the vampires from the meadows, starving while the elite thrived. Eleanor and Ralph grew up in the shadow of it all. Each of them has a reason to fight. But none more than Eleanor. She wears the face of the enemy. Her allies don’t trust her. Some want her gone. But she doesn’t need their approval. She’s inside the Shining City now. Deep behind enemy lines. While the Steel Lady watches for the army outside her walls, Eleanor will be waiting inside—ready to put a blade to her throat. By the time the regime sees the true threat, it’ll be too late. Inside These Walls is the explosive twentieth book in the Beyond These Walls saga—a relentless post-apocalyptic thriller perfect for fans of The Hunger Games , The Maze Runner , and The Last of Us .
