In Toronto, 2050, a city of 200+ cultures makes an impossible choice—and elects its first humanoid mayor. HMayor—416 is not built to blend in.

In a fractured world where life rises and disappears without memory, one presence remains. Rooted deep within a silent divide, an ancient tree endures—watching the endless cycles of emergence and fading that surround it. Nothing lingers. Nothing returns. Everything passes…except the tree.

What once defined its apartness begins to reveal itself as something else entirely. Strength.

And how do you even escape a place where outside doesn’t exist?

At the center stands Maze’sar’tall, captain of the Huntress. Barefoot, dagger in hand, she refuses every crown and every chain. Neither queen nor warlord can tame her. But in the void, something darker watches—patient, eternal, waiting to strike. Betrayal. Survival. Legend.

Everyone knows that fleeting shiver — the sense of living through a moment you could not possibly have experienced before. A déjà vu. For neuroscientist Elias Soler of Barcelona, it is no accident. It is the greatest discovery of his life. Perhaps the most dangerous.
