Black Canyon Conspiracy (Harlequin Intrigue Series #1590)

He'd rescued a beautiful hostage, now he needed to keep her alive 

Former Special Forces soldier Marco Cruz has no time for messy emotions. But the beautiful TV reporter he saved from a hostage ordeal now faces graver danger. Someone wants Lauren Starling dead—and the sinfully handsome Ranger wants to be the one to protect her. 

Teaming up to find a killer and bring Lauren's kidnapper to justice, Marco and Lauren go on the run—outside the law—in a harrowing race for their lives. Before long, Marco begins to have unfamiliar feelings for Lauren—admiration, sympathy…and a powerful lust. He knows what's going on between them is unprofessional. But also undeniable.
