The Spinster's Guide to Scandalous Behavior by Jennifer McQuiston

In New York Times bestselling author Jennifer McQuiston's enticing new Seduction Diaries entry, a mysterious journal may provide a potential spinster with instruction—or lead her to her heart's desire

Free-spirited Lucy Westmore isn't yet a spinster, although she fully intends to be. Fortunately, an eccentric aunt has left her both a diary detailing the secrets to spinsterhood and a cottage in Cornwall. Unfortunately, an insufferable marquess is angling for her prize! Turning Lord Thomas Branston down flat should be easy. So why does this man who won't take no for an answer make Lucy's body and soul sigh yes?

Thomas knows the real value of Heathmore Cottage, and he has no intention of letting some silly Society miss get her hands on it. He'll simply have to charm Lucy into selling. But the clever young woman he encounters, first in London, then en route to Cornwall, stands stubbornly on her own two (quite lovely) feet. And now, Thomas can think only of sweeping her off them.
