The Centauri DeviceM. John Harrison
science fiction > space opera
Captain John Truck was to all outward appearances just another spaceways hobo. So why should both sides in a vicious space-war be so murderously anxious to secure his co-operation? The answer was that only Truck held the key to the working of the most destructive and mysterious weapon ever made. But he wasn't very eager to trigger off Armageddon.
Not at first, anyway...
The Centauri Device is a galaxy-spanning novel of intrigue and violence in the great tradition of the all-time classics of science fiction adventure. M. John Harrison, one of the most brilliant of the new generation of SF writers, has created a story of interstellar excitement to stand comparison with the works of E. E. 'Doc' Smith and A. E. van Vogt.
