The dream is ending.
It started with flickering trees and vanishing islands. Now the sky itself is cracking. The Dream Sanctum-the shared paradise where Kai, Lindsay, and Kwin found their power and their friendship-is slowly collapsing.
What's more, mysterious messengers have returned with a desperate plea: The Sanctum needs its Keeper, a chosen dreamer, to stabilize the world. But the intended Keeper has been gone for years, and the world does not have the strength to choose another.
As cities fall and waves swallow islands, Kai and the others begin a desperate search to find the only one with the power to save the world from vanishing into nothing. But as they get closer to finding what they seek, they also uncover a terrible truth:
Saving the Sanctum this time doesn't mean fighting a monster. It means making a sacrifice.
