When he rebelled against his father, Edmon Leontes lost everything, but a lot has happened in the twelve years since he left his remote home planet of Tao. He has made a new life for himself as the medic aboard a starship, earning his keep traversing the galaxy with a misfit crew. Edmon thinks he has left his tumultuous past behind him, yet all that changes when his father dies.

Phaestion, the man he once called brother, has inherited Edmon’s birthright. But Phaestion’s ambitions of domination are not limited to Tao, and he is not inclined to let a rival—even one in exile—continue living. Phaestion’s pursuit of power spans the universe, running afoul of powers no one is fit to be meddling with. Edmon will need to confront his past as he and his crew race across worlds to uncover the origins of the Fracture…and save the universe from complete destruction.
