Pandora’s Star by Peter F. Hamilton
The Commonwealth Saga
The year is 2380. The Intersolar Commonwealth, a sphere of stars, contains more than six hundred worlds interconnected by a web of transport “tunnels” known as wormholes. At the farthest edge of the Commonwealth, astronomer Dudley Bose observes the impossible: over one thousand light-years away, a star . . . disappears. Since the location is too distant to reach by wormhole, the Second Chance, a faster-than-light starship commanded by Wilson Kime, a five-times-rejuvenated ex-NASA pilot, is dispatched to learn what has occurred and whether it represents a threat.
