It Happened One Autumn

Four young ladies enter London society with one common goal: they must use their feminine wit and wiles to find a husband. So a daring husband-hunting scheme is born. 1841. Annabelle Peyton, determined to save her family from disaster, decides to use her beauty and wit to tempt a suitable nobleman into making an offer of marriage. But Annabelle's most intriguing--and persistent--admirer, wealthy, powerful Simon Hunt, has made it clear that while he will introduce her to irresistible pleasure, he will not offer marriage. Annabelle is determined to resist his unthinkable proposition...but it is impossible in the face of such skillful seduction. Her friends, looking to help, conspire to entice a more suitable gentleman to offer for Annabelle, for only then will she be safe from Simon--and her own longings. But on one summer night, Annabelle succumbs to Simon's passionate embrace and tempting kisses...and she discovers that love is the most dangerous game of all. (Source: fictiondb)

From fictiondb: A DEVIL'S BARGAIN Easily the shyest Wallflower, Evangeline Jenner stands to become the wealthiest, once her inheritance comes due. Because she must first escape the clutches of her unscrupulous relatives, Evie has approached the rake Viscount St. Vincent with a most outrageous proposition: marriage! Sebastian's reputation is so dangerous that thirty seconds alone with him will ruin any maiden's good name. Still, this bewitching chit appeared, unchaperoned, on his doorstep to offer her hand. Certainly an aristocrat with a fine eye for beauty could do far worse. But Evie's proposal comes with a condition: no lovemaking after their wedding night. She will never become just another of the dashing libertine's callously discarded broken hearts -- which means Sebastian will simply have to work harder at his seductions...or perhaps surrender his own heart for the very first time in the name of true love.
