Drachen (A Matthys Rossouw Pursuit Book 1)

A marine archaeologist standing-up for herself. A psychopath with mother issues. A hitman who hates failure. A soldier with a point to prove. A policeman out on a limb. And a treasure that tests every allegiance.

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.
