Ruler of the nanites (STAR-DUST 5)

Sigurd Westall has been abducted from the Venus station TRISHARANA by alien intelligences. While the Mernchen, an alien race, continue to infiltrate the Life-Int-Ltd. on Earth, the organic spaceship Paurusheya wants to start the search for him immediately. However, Sir Arthur Newcraft cannot justify losing the only connection to Earth. Sigurd is sent to the nearby Epsilon Eridani system, where the Xxiin people ask him for help against an overwhelming enemy. At the same time, he makes a stunning discovery that elevates him to ruler of the nanites.
