After returning to Esprit, the hunt continues. But this time, the world is ending. Still on the run, the kids realize the Empire will do anything to capture them, and their fight to survive suddenly becomes a fight to protect the entire planet. But how do you save a world that’s against you? With a bounty on their heads, nowhere is safe, and the stakes rise when Delphi’s prophetic visions guide them to the one thing that can save Esprit from the edge of disaster. Now, they must go on a journey that takes them to the planet’s center in search of a way to save themselves and the world. Will they make it in time? Or will the world die with them? Join the crew as they wonder if Delphi’s visions are leading them to safety or into a trap while they set off on a voyage that will take them farther than anyone has ever gone before, into Esprit’s core.
