Following in the footsteps of the masters of the ancient Je'daii Order, Lanori Brock learns the secrets and possibilities of the Force. A power that her brother was not given to wield. Deprived of any sensitivity to its currents, he experiences only a bitter aversion to the art of the Je'daii, which ultimately leads to tragedy. After many years spent wandering the Galaxy, Lanori receives an urgent call to the Je'daii Council. Some fanatic, the head of an entire cult obsessed with traveling beyond known space, got into the habit of opening space gates using terrible dark matter and thereby risking causing a cataclysm that could destroy an entire star system. Even more than the prospect of galactic catastrophe, Lanori is amazed that it is she who is tasked by the Je'daii Masters to prevent this nightmare. And then a stunning revelation makes her realize why she was chosen. The brilliant madman she must track down and stop at all costs is her own brother. The brother whose death she had long mourned and whose life now fills her with horror.
