The Duchess of Love (Duchess of Love‪)‬

The day was as hot as the pond was inviting. It's not as if anyone in
Little Huffington was going to happen upon a secluded vale on the Duke
of Greycliffe's lands. And Venus Collingswood didn't want to get her
shift all wet. It was the perfect setting in which to plan her lovely
bookworm of a sister's betrothal to the mysterious new duke arriving
seven days hence. If only she had a suitable accomplice . . .

Andrew
Valentine, Duke of Greycliffe, never thought arriving at his own
household a week early would cause so much trouble. The housekeeper
thinks he's his own cousin. Actually, the chance to not be the duke for a
while is a pleasant opportunity indeed. It might even help him
interrogate the delectable little nymph he's discovered swimming in his
pond—if he can manage to get a word in edgewise . . .
