Two civilizations. Two truths. One war waiting to ignite. Aiyana Waketah has just earned her place among the Harmonic Engineers of the Many Nations Alliance, where living towers harvest the wind and golden eagles share their sight with bonded companions. On the morning of her greatest achievement, an unknown signal tears through the Bioweb. Tower Seven collapses. Fourteen engineers die. The fragile peace between two civilizations begins to crack. The attack came from the Pale Cities to the east, where a different civilization tells a different story about history. Elias Harren is a young Pale Cities attache assigned to research Alliance aggression for an upcoming summit. What he finds in the archives shakes everything he believes. The history he was taught is not incomplete. It is invented. At the summit, Aiyana and Elias find themselves on opposite sides of a negotiating table rigged to fail. Someone wants war. And somewhere in the gray lands between their worlds, Aiyanas missing brother holds secrets both sides would kill to possess. As borders harden, Aiyana must transform from idealist to defender. She carries evidence her enemies will never acknowledge. She has an unlikely ally in a man who should be her enemy. And she is beginning to understand that the greatest threat is not the weapon that destroyed Tower Seven, but the lies that made it possible.
