When Dr Trehearn Culver is awoken from cryogenic stasis only to find the rest of his colleagues have mysteriously died, he becomes the sole survivor aboard the 'Emissary', a vast star ship on a mission to colonise a far off planet. Battling his solitude and compelled to carry on his mission to appease his only companion, Adraste, the ship's 'thinking computer', Trehearn travels down a road of scientific research and ethically questionable experimentation. Believing himself to be the only hope of rekindling his species that have reduced themselves to near destruction, Trehearn's genial aptitude and tireless efforts look to have achieved the impossible, but then even the best laid plans can be doomed for failure. 'Emissary' is an imaginative and thought provoking science fiction thriller from the author of 'Dark Phase'. The novel contains scenes unsuitable for younger readers.
