As it turns out, quite a lot.
Ross and Damon Fraser are brothers on an elite caving team attempting a new world depth record, but the wheels come off the moment they arrive in the tiny breakaway republic of Abkhazia. Akhar Kutsnia, head of the country’s shadowy intelligence network, throws them in prison and gives them an ultimatum.
Damon, a lawyer for the CIA, will remain on the surface to ferret out who is meddling with Abkhazia’s upcoming election, while Ross continues down the cave with the team. If Damon refuses to help, or is unsuccessful, Ross will not make it out of the cave alive.
Thrust into Kutsnia’s murky world of covert ops, Damon teams up with Kari Howland, an analyst out of the CIA’s London office. Together, as the election ticks ever closer, they begin to peel back the layers of a deadly conspiracy.
