In a city hidden beneath the earth, two forces shape existence-gusters tear things down, and blockers build them back up. It's an unbroken cycle. A perfect balance. And no one questions it. Until Jasmine disappears. There is no announcement. No mourning. No trace of her ever existing. But Jade remembers. And she refuses to let her sister slip into forgotten silence. As whispers of the Gardeners stir in the deepest tunnels, and a stolen baby dragon hints at a long-buried past, Jade begins to unravel a truth never meant to be unearthed. The balance isn't natural-it's controlled. And if she exposes it, she may lose more than just her sister. Because something ancient is waiting in the dark beneath their world. And it remembers everything.
