The Hidden Target (Robert Renwick Series #2) in Bloomington, MN

For Nina O’Connell, a trip round the world was the holiday of a lifetime. Travelling in a group led by the attractive James Kiley and his friend Tony Shawfield, she is surprised when she runs into an old flame on a sunny Amsterdam street. But Robert Renwick, ex-army major attached to NATO, is not there by chance. He is on the hunt for two terrorists who have left a trail of bombings and murder in their wake, and now he must keep Nina safe while trying to discover their next target.
Soon Nina is caught up in a grim game of life or death that stretches from the back streets of Bombay to the highest reaches of Washington’s political elite.
