Sweet Devil by Lois Greiman

Linus Jeremy Shepherd, mercenary, ex-Ranger, and all around thrill seeker, is shocked when Carlotta Osorio arrives on the doorstep of Eddy’s Angels Detective Agency. Yes, she saved his life while he was held captive in the jungles of Colombia, but she also broke his heart by returning to the very same drug lord who’d captured him. Now he’s certain the sultry senorita hopes to deliver him back into the hands of the madman who tried to kill him months ago. But whether he admits it or not, he can’t resist a damsel in distress…even if she is planning to get him killed.

Carlotta Elaina Padilla-Osorio is terrified. Her sister Sofia is missing, and although Lotta has vowed never to demean herself by seeking Shep, who she believes abandoned her without a backward glance, circumstances demand that she swallow her pride and do just that. Will they find Sofia before it’s too late or will the mistakes of their past destroy them all?
