Hot Target (The Echo Platoon Series, Book 4): Military Romantic Suspense

A cruise-ship romance with Navy SEAL Tristan Halliday was one thing, but now he's back, wanting more. His can-do attitude—and mouth-watering sex appeal—make him hard to resist, and she could use his special skills to hunt down her parents' murderer. But Private Investigator Juliet Rhodes prefers being single, and working alone.
Unfazed by Juliet's bristling independence, Tristan helps her scour San Francisco's art district, finding and confronting top suspects. The deeper they dig, the greater the danger, and just as they close in on their target, Juliet slips through his fingers, leaving her vulnerable to the killer's revenge.
