For the Love of the Baron. The Noble Hearts Series, #3

This book is 100% created by the author. No AI was used. They never expected a tug of war for a book to end in love. Lady Marigold is the last of the Earl of Pomeroy's three daughters to be married off. Although when she was younger, Marigold had dreamed of love and marriage, since then she has never found a man as intelligent as she is or who treats her like more than a feather-headed piece of fluff.
The single state is fine for her. Jonathan, Lord Stanley, belongs to the same elite book club as Lady Marigold, who annoys him to no end. Although pretty and friendly, in his esteemed opinion, she is nothing more than a nonsensical chit who doesn't deserve membership in their exclusive club. When they both appear at an estate sale and attempt to buy the same journal of a deceased member, a man well-respected in the science community, a tug of war begins.
The battle for the book throws them into murder, danger-and passion.  Something neither of them expected...
