The Sigian Bracelet by George Tome

On a beautiful summer morning, a thousand years before the start of our story, the fleet of an advanced civilization arrived on the Antyran home planet. It wasn’t a pleasant encounter – at least not for the Antyrans, because the aliens burned their ice cities to the ground and locked the whole star system inside a space distortion that held them captive ever since, hiding the stars.
And then, on another beautiful day, the discovery of a few fragments from an ancient spaceship buried in a ravine will open up the chest of madness.
Gillabrian, or Gill, as friends use to call him, is an Antyran archaeologist. After stumbling upon the terrible secrets of the alien visitors, he finds himself in the unenviable position of being hunted on all the Antyran planets, and not only there.
Will our hero prevail and find a way to keep the secrets of the Sigian Bracelet?
