Secrets of a Summer Night — Lisa Kleypas

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.
