Ken Follett - The Hammer of Eden / Triple

Ken ​Follett hits the top of his form with The Hammer of Eden, a state-of-the-art suspense thriller to rival his best.
When controversial radio talk host John Truth broadcasts a terrorist threat of a man-made earthquake, few people take it seriously. Crackerjack young FBI agent Judy Maddox is assigned to track down the elusive, sinister group called the Hammer of Eden.
Judy's boss, who has a grudge against her, thinks he has given her a waste-of-time assignment. But Judy's research leads her to maverick seismologist Michael Quercus, who gives her the shocking news that it might just be possible for an earthquake to be deliberately triggered. And when a tremor in a remote California desert shows evidence of being machine-generated, Judy knows the threat is terrifyingly real.
Suddenly in charge of a life-or-death investigation, Judy must pinpoint the terrorists' next target, with the help of the erratic but attractive Michael. Their compelling romantic drama is played out as they race to beat the terrorist deadline and prevent an unthinkable disaster.

Triple:

The world's balance of power is about to shift dangerously as the ultimate weapon nears completion in a secret facility in the heart of the desert. Across the globe, operatives from the great nations set a deadly game in motion, covertly maneuvering pawns and kings to achieve a frightening advantage—while terrorists and their hunters prepare for the contest's final bloody moves. And one man—a razor-sharp master of disguise, deceit, and triple-cross—must somehow do the impossible: steal 200 tons of uranium without any of the other players discovering the theft.

The clock is ticking. And the price of failure is Apocalypse.
