He escaped from a terrible imprisonment and was protected by Maelen, the Moon Singer. A weaver of thoughts, she was, Krip know both gentle and powerful and he was persuaded by her to discard his human body so that his inner being might assume a shape unrecognisable to his enemies.

Soon such compensations that his new nature offered were replaced by a fear greater than his mind had ever known in Space. A hunted animal, Krip sought desperately to regain his human form before his companions, the Free Traders, lifted their ship towards the Galaxies once more . Brilliantly told by a leading science fiction writer, this is an adventure story which explores the farthest reaches of space and psyche.
