Fool’s Run [EPUB ebook] 

Somewhere in a far galaxy a being inconceivably alien is surging tumultuously from an unimaginable womb.In a solitary prison cell on the Underworld, the vast prison-satellite in perpetual Earth-orbit, Terra Viridian is tormented by a vision, an imperative which has already driven her to an insane bloodletting.On an Earth embalmed in peace by a ubiquitous bureaucracy, the Magician weaves his musical spells and tried to close his mind to the thoughts of others. — just three links in a chain stretching across space and time towards a testing as awesome as it is unpredictable.
