The Key To Her Heart by Blanche Dabney
This is entertaining, suspenseful and romantic. Daisy went to MacGregor Castle to deliver a package to Jock MacGregor that her sick roommate was supposed to bring. Jock thought Daisy was an assassin, so he threatens to kidnap her if she dares to come back again after the second time she ends up up at his bedroom door. But Daisy isn't in complete control of her travel plans. Jock is also dealing with the quick decline of his parents, and that someone stole the clan's money. Jock is a little oblivious to what's going on around him, Daisy is too eager to do what she loves without thinking of what she has to give up. This is an intriguing series and each book is better than the last.
I received a complimentary copy of this book from the author. This is my honest and voluntary opinion of it.
