The Magic Chessman - Kenneth Tucker - Bog

He was a mere pawn, a being manufactured by an alien race, the ancient Relvans, and transmitted to Earth to be their agent, a knight who would save this world from the evil Grakanni, an alien race that travels the galaxy looking for worlds to enslave. But something went wrong as his essence was transmitted to a Relvan star platform orbiting Earth-a Grakanni disrupter beam's attempt to destroy the Relvan star platform and prevent his arrival, while failing to stop the transmission of his substance, nevertheless left the reassembling of his psyche incomplete.
And as his mind wrestles with the mixed-up memories of the three Earth men the Relvans mined in his creation, this man without a name struggles to fulfill his mission to save the Earth while rescuing a damsel in distress and destroying the men and women of Earth who would become rich and powerful by assisting the Grakanni in their destructive pursuit. Reminiscent in style of the works of H.G. Wells and Edgar Rice Burroughs, The Magic Chessman presents a complex tale of a man tasked with becoming a hero by circumstances even as he searches for his own soul.
