Three friends from a mission many years ago reconnect when one of them dies on Ascension Island. Rory Bannatyne had been tasked with tapping a new transatlantic data cable, but a day before he was due to return home he is found hanged. When Kathryn Taylor begs Kane to go over and investigate, he can't say no, but it's an uneasy reintroduction to the intelligence game. Ascension is a curious legacy of England's imperial past. Only employees and their families are allowed to live there. It's home to several highly-classified government projects, a British and American military base, and forty dead volcanic cones. Entirely isolated from the world, the disappearance of a young girl at the same time as Rory's death means local tensions are high. Elliot needs to discover what happened to her as well as to Rory. But the island contains more secrets than even the government knows.
