Lady Geraldine Sandhurst, Gerry to her friends, is an alumnus of Miss Vines School for Young Ladies. During one of her last years there, she read a scandalous book that no proper young lady should ever read. With no practical experience of men, she had no frame of reference for the acts portrayed in the text. Once on the marriage mart, the book is never far from her thoughts. And when a mistaken encounter in a secluded alcove opens her eyes to what passion is, she is suddenly very curious about the world of men and passion. All she needs to do is avoid ruining her reputation with a rake like Lord Harbourne. The Marquess of Harbourne is a rake, a rogue, a libertine, and he loves it. He has no inclination to get involved with innocent ladies and fall into the marriage trap. When he realises the lady in the alcove is not the experienced lady he had planned to meet, he sets out to discover who she is. He finds an inquisitive and passionate young innocent who knows things a lady of her experience should definitely not know. He should avoid innocent ladies, but this one is too tempting by far. Especially when she does something only a doxy should know about, and he falls in love with her. During a hunting party at Carson’s Hall, Gerry is mixed up in another case of mistaken identity which has life-changing consequences. Can Harbourne help her out of this mess she’s in? Or will she lose him forever when she is forced to marry another? And what is a Chelsea Turnpike?
