A girl missing in New York. A political bombing in Iceland. No ordinary cop would see a connection. But Detective First Grade Brian McKenna didn't earn his reputation by being ordinary. In Once In, Never Out, McKenna travels the globe in pursuit of his darkest foe yet--a terrorist bomber whose next target could be New York's St. Patrick's Day Parade. Along the way he finds a good friend and cunning ally in Thor Erikson, Iceland's sole homicide detective. This is a case that brings McKenna to the edge of his abilities, and puts both his detecting and survival skills to the ultimate test.
