Kiss or Kill (Silhouette Romantic Suspense Series #1488)

Special Agent Renee LeBlanc was deep undercover, close to exposing the leader of a terrorist cell. Then he showed up in the midst of her op. Mark Alexander, the only man who had ever upset Renee's uncanny instincts—a man who could blow her cover with a word. The desire between them was as strong as ever, but who was Mark really—ally or foe? Hero or villain? Lover…or assassin? These were decisions she had to make.

Heaven help her if she was wrong.
