"At sunrise on the day she would die, Ginny Hill flew fast and low along the border to save a spy with no name hiding from his enemies in a field of stones."

When a British Army helicopter crashes in a lake in Wales, killing the female pilot, questions naturally arise. Was this terrorism? If so, who were the terrorists? And why did certain people never admit they had an agent on board - one they wished dead?

All too soon, the law of unexpected consequences kicks in, and the pilot's death triggers the unravelling of five secret but interlinked lives, including that of her radical clergyman father.

Moving at pace between Northern Ireland, Scandinavia, South Africa and South America, this Russian doll of a story builds to a brutal conclusion... but one with a wickedly unexpected twist in its tail.
