Running Target by Elizabeth Goddard

She escaped right into danger...

A routine patrol turns deadly when marine deputy Bree Carrington's boat is sunk by men carrying illegal weapons. Fleeing a barrage of bullets, she's suddenly rescued by DEA agent Quinn Strand - her ex-boyfriend. Quinn's return threatens more than Bree's heart...because he's the one the men are really after. As criminals hunt her to get to him, can Quinn and Bree take down a drug ring?
