In this imaginative and amusing sci-fi novel, the Earth has been contacted by aliens and invited to work toward joining the galactic council, a united nations for the sentient galaxy. A pretty-smart couple, Tom and Lucy, are sucked into inter-species intrigue, and use their sharp human wits to escape some close calls, set right some wrongs, and ultimately help humans on their way to joining the galactic brotherhood. Dickson, a longtime master, uses his imagination for aliens and their problems to good effect. The weakness of this novel are the characters, who seem mired in 1950 with stilted gender roles, excessive politeness, and a general feeling of June and Ward Cleaver go to other planets. Much of it is done for humor, so even the bad is sort of good.
