Wing Commander

The descendants of the first ones to travel space are regarded as people of lesser worth. Half a millennium after the first ships launched in search of a better life, the Pilgrims still are discriminated. When the Kilrathi declare war against the human race, it is up to Christopher Blair, Pilgrim halfling, to help avoid complete annihilation. Since the Kilrathi managed to conquer a Navcom unit, they know the jump coordinates to Earth. And since the terran fleet is two hours further away from home than the Kilrathi fleet, the only hope of Mankind is to set trust in a Pilgrim, who can astrogate by feeling and does not need a Navcom unit - it's all genetics.
