Before I write my review, let me just give all other potential readers a heads up. You should first read "The Rogue Who Rescued Her" and "Home for the Holidays" (found in the anthology "Tis the Season by Jennifer Ashley) as this book is the continuation of the two aforementioned books. If you read those two books first, you won't be lost when you read this one.
A Lady’s Guide to a Gentleman’s Heart, Book 2 of The Heart of a Scandal series, was about Lord Heathcliff "Heath" Whitworth, the Marquess of Mulgrave and heir to the Duke of Sutton, and Lady Emilia Aberdeen, the daughter of the Duke and Duchess of Gayle, and goddaughter to the Duchess of Sutton.
Emilia had once been engaged to His Grace Connell Wordsworth, the Duke of Renaud, Heath's best friend, only for him to suddenly cry off for reasons known only to him and Heath, leaving Emilia to deal with the rumors, conjectures, ruination, and scandal for the next ten years.
During a house party thrown by his parents, Heath, who had wrestled with his feelings for Emilia for years, was tasked by his mother to see to it that Emilia "had a good time". She even went so far as to write him a "to-do/not-to-do list for him to follow when interacting with Emilia. To say that Heath was reluctant to spend any amount of time with her would be putting it mildly. He protested strenuously against his mother's machinations, mainly because she was his best friend's former betrothed. Due to that illustrious title, Emilia was to be considered off-limits...at least by him.
For her part, Emilia had always been frustrated by her former betrothed's ever-present, totally staid best friend. But as she was getting to see a different side of Heath while at the house party, her opinion of him started to change. When Emilia spotted Heath's to-do list that he had unknowingly dropped, she set out to have a little fun with it. Using the list against him, Emilia began subtly teasing him, which put the ever-staid lord at "sixes and sevens", much to her amusement and his discomfort.
Unknown to her family, friends, and even Society, Emilia was the anonymous author of a column that offered advice to young ladies regarding how to win a gentleman's heart and how to discern a gentleman from rogues, rakes, and cads.
Heath, too, was beginning to see a side of Emilia he did not know existed. He had always seen her as a young debutante that thumbed her nose at Society, believing she had been free to live as she wanted while he, on the other hand, had been collared by the studying of his duties as the ducal heir.
Having been tricked into kissing Emilia under the mistletoe by his nieces, Heath struggled with guilt. Since she was the former betrothed of his best friend, he didn't know the rules regarding how to act around her, especially as his feelings had never changed but now seemed to be growing in strength.
As they proclaimed their love to each other, the past reared its ugly head and sought to part them. Anguish, fear, and concern were some of the other emotions that filled this story, along with humor, joy, passion, and happiness.
The characters were well-rounded and fleshed out...as well as likable. The storyline had a firm foundation, very little fluff, and the flow was smooth and easy-going. The ups and downs of the relationship were so close to reality that it was like watching a true-to-life relationship play out on every page.
This was definitely five-star worthy, and the book will be added to the Keeper for the Shelves collection.
