To Save One World, They Had to Destroy Another!
Hannibal Fortune, archeologist turned debonair secret agent for the Temporal Energy Restructure and Repair Agency, found himself in 1500 BCE facing the worst assignment of his career: Wreck the great and beautiful civilization of Mohenjo-daro.
The tyrannical forces of EMPIRE were tampering with the timelines again, trying to alter history so that Hannibal and T.E.R.R.A. never came into existence! History showed that Mohenjo-daro had fallen to an invading horde of barbarians from the west. So the bad guys were trying to save this earliest of civilizations, while the good guys schemed to destroy it. Whether he liked it or not, Fortune had to aid the barbarians in their attack on every value he held dear.
Meanwhile, his partner, Webley, the caustic shape-changing symbiote, finds himself working with another of his kind from T.E.R.R.A., leading to a competition between the two aliens played by the strangest rules in the galaxy. Here is another delightful romp through time from the pen of the legendary SF humorist, Larry Maddock (penname of Jack Owen Jardine).
