-White House Protection Force Romance #1-
The White House Protection Force Saves the Day! Come meet the behind-the-scenes specialists who keep our White House safe—even while they lose their hearts.
White House Chocolatier Clive Andrews takes pride in the subliminal messages hidden in his State Dinner showstoppers. But there’s more than sensual sweets at risk when his heart begins to melt.
Sergeant Linda Hamlin left the Army after a decade of service. As the newest member of the U.S. Secret Service K-9 Team she expected flak. She didn’t expect to be paired with a misfit mutt named Thor. Together they face down bombers, master spies, and a teenage genius.

All of which might be manageable, if not for the handsome chocolatier who teaches her that a little indulgence can be a very good thing.
