Kaiden Cross was nineteen when an accident put him in a coma. He woke up, rebuilt his life, and spent three years trying to be normal. Then the dreams came and normal stopped being an option. Through them he meets Gia, who tells him the truth. He is the last Kaelix. The only person alive with the power to stand between humanity and the things hunting it from the other side of reality. Three realms exist beyond what the living can see. The Liminal, where the dead find peace. The Cilios, where something ancient and imprisoned feeds on every soul that never makes it there, dragging them through the Echoing Wastes, the Shadow Depths, the Void. And the girl he loves is trapped inside it. To reach her, Kaiden masters powers no human was built to carry. Soul unbinding. Mind walking. Dream walking. Realm travel. Teleportation. Precognition. Multi-dimensional projection. He fights every villain a god-level entity throws at him and walks away from all of them. But one battle breaks time itself. Something goes wrong that can't be undone in the present, only in the past. Now Kaiden has to travel back, navigate a timeline that doesn't want to be changed, and fix a mistake that could cost him the only person he's been fighting for all along.
