New York Times bestselling author David Hagberg pits The Expediter's Kirk McGarvey against people who mean to destroy our future in Abyss.

It's a pleasant summer afternoon off Florida's east coast, where NOAA scientist Dr. Eve Larsen is on the verge of a breakthrough. Not only does she have the answers to climate change, she also has the technology to stop killer storms across the planet.

At that moment, contract killer Brian DeCamp walks into the nearby Hutchinson Island Nuclear Power Station, aiming to cause a meltdown more devastating than Chernobyl. Luckily, former CIA director Kirk McGarvey manages to thwart the catastrophe. But the failed sabotage sets off a terrifying chain of events as McGarvey follows a trail of assassinations and dirty money that leads to power brokers who will stop at nothing to see Dr. Larsen's project fail--enemies far more ruthless than McGarvey could ever have imagined.
