A psychopath with mother issues. A policeman with his career on the line. A beautiful agent with unclear allegiances. And an ancient organisation guarding a secret that could get them all killed. Hiko Shimuzu is not a nice man, but he is ingenious. Is he ingenious enough to find a lost artefact capable of catalysing a revolution in China? Maybe. And that's close enough to draw the attention of powerful forces that won't hesitate to kill to keep their secrets safe. Meanwhile, Matthys Rossouw is in hot pursuit, unaware of the full scale of the danger he faces. Butterfly Hill is the exciting follow-up to Drachen. Set in the hills above Hong Kong's Lantau Island, it's another high-stakes game of cat and mouse that races towards an explosive conclusion. Seven hundred years ago a Dynasty died. How far will people go to keep it that way?
