Brett Rivera has spent three years searching for the Drachen. The day she finds it is the day her life changes: there is no sign of its legendary treasure and now a cold-blooded killer is hunting her. What does he know that she doesn’t?

Brett is chased in Finland, double-crossed in Tallinn, abducted in Lübeck, and shot at in Bremen as this action-packed thriller dashes across northern Europe, barely pausing for breath.

A shipwreck. A lost treasure. A hell of a race from one to the other.

A psychopath with mother issues. A policeman with his career on the line. A beautiful agent with unclear allegiances. And an ancient organization guarding a secret that could get them all killed.

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 toward an explosive conclusion.

Seven hundred years ago, a dynasty died; how far will China go to keep it dead?
