Spy Fall by Diana Quincy
I received a free copy of this book in exchange for an honest review. This is full of wonderful intrigue, twists and turns, very smart wise cracks, and a lot of action. Mari has been charged with finding a list of English spies that Aldridge supposedly has and is turning over to the French, she parachutes onto the property as her cover, and right into Cosmo, the heir. While investigating, Mari attracts Cosmos attention and he becomes suspicious of her. Is Mari right? Is Cosmo right? The story keeps you turning the pages to find out.
