Throughout the civilized galaxy, in spacers' ports on the most far flung worlds, an ancient Terran legend echoes...about a race of magical beings called the Little People or the Fairy Folk. What if there is truth behind the old stories and songs? What if such a race really exists, fleeing from world to world one step ahead of mankind's ships?
