Something in the Water by Catherine Steadman

A young British couple goes through a financial crisis just as they approach their wedding and honeymoon to Bora-Bora. The days and nights are magical until a dive trip where they make an unusual discovery that will change their lives forever. A canvas bag filled with money and diamonds in a plane wreck without survivors falls into their hands - what could go wrong? They try to return to their normal life where Erin works as a documentary filmmaker interviewing prisoners. Are the police watching them? Do the criminals know what happened to their stuff? The choppy writing style adds to the frenzy of planning a wedding, a job loss and this incredible turn of events. It all happens so fast that they begin to question each other and you start to look for more than one bad guy. I wouldn't read this thriller on the way to an island paradise.
