One is One — John Rankine

Senior Controller Dag Fletcher was beginning to feel very angry with the whole pointless business. What had begun as a commercial and training flight aboard the old I.G.O. corvette Interstellar X had gathered such complications to itself that the mission was drifting towards a first class muddle. The planet looked bad enough. They were awkwardly placed in their makeshift silo. Land survey was not going to be a picnic. But he had to find a site and leave it equipped as the local consulate. Complications began straight away in the shape of Vernon Spencer, the Corporation Chairman's nephew. He was being given his last chance to shine. Then Vanora joined the ship... This is the fifth book in the Dag Fletcher Galactic series.
