Fiancé by Friday (The Weekday Brides, #3)

Gwen Harrison:
The beautiful, high-born daughter of an English duke came to America to take over her sister-in-law’s matchmaking business. But just because she’s the boss doesn’t mean she can’t fantasize about making her own perfect match with bodyguard Neil MacBain. Will the enigmatic man who haunts her dreams cost her more than she bargained for?

Neil MacBain:
The retired Marine can’t deny the effect blue-blooded Gwen has on his troubled soul or his battle-hardened body. But as a client, Gwen is off-limits—until a threat from Neil’s past returns…and Gwen is caught in the crossfire. Now to keep her safe he will risk it all: his career, his life…and his heart.
