Description

A dream vacation. A perfect anniversary. A killer hiding in plain sight.

When Derek and Brianna Murphy set off on a romantic river cruise from Passau to Budapest to celebrate twenty-five years of marriage, they expect historic cities, candlelit dinners, and a much-needed reconnection. What they don't expect is the instant bond they form with two other couples-strangers who, over shared excursions and late-night conversations, begin to feel like lifelong friends.

But friendships forged on calm waters can shatter in dark depths.

On the final morning in Budapest, the body of a passenger is discovered drifting in the Danube-an apparent accident that quickly proves anything but. When Peter Andrassy, former NYPD detective turned investigator for the Hungarian National Police arrives, he is tasked to untangle a web of secrets that followed the tourists ashore.

Can Peter find the killer and bring them to justice? Or will he become a victim himself?
