The classic tale of terrorism, where a criminal fanatic is hell-bent on blasting San Francisco into the ocean, from the acclaimed master of action and suspense.

'Earthquake country,' said the Professor. 'San Francisco is geologically and seismologically a city that waits to die. Los Angeles is ringed by earthquake centres – seven massive quakes so far. We have no idea where the next, the monster, will hit…'

…until a criminal fanatic kidnaps a nuclear scientist and builds his own atomic bombs. If exploded on California's fault lines they could trigger off the mightiest earthquake of them all – killing half its population and dumping the entire city of San Francisco into the sea.

Goodbye California…
