Once the fuse is lit, theres only one way to extinguish the flames. In the Line of Duty, Book 1 Years ago, Cole Sullivan made a battlefield promise sealed in a dying mans blood-to take care of his best friends little sister. Now hes forced to live with the fact that Gemma Matthews is completely off limits. Though Gemmas always had a crush on the darkly handsome, far-too-serious explosives expert, she cant forget the sting of his rejection. Now here they are, ten years later, with Cole still stubbornly in the role of protector. But when she catches him watching her from his house next door, she jumps at the opportunity to show him everything hes been missing. Cole can barely keep his cool at Gemmas bedroom window performance. Hes never been a risk taker, but her all-out campaign of seduction ignites a fuse that can only blow up in his face.
