Green Beret Bodyguard (Harlequin Intrigue Series #1326)

He may have lost his memory, but not his mercenary skills. And once Jack Coburn learned his real name, he sought out the woman who could help him piece together the rest of his past. Lola Famosa had hired the green beret months ago to find her missing brother. And that mission had nearly cost him his life.

But locating the lovely doctor presented new dangers. Someone was determined to keep Lola from her quest, and her life hung in the balance. Jack's first concern might have been regaining his memory, but now it was all about protecting Lola. For she was the one thing this loner was determined to keep.
