Before the season ends / Linore Rose Burkard.

Enhanced descriptions from Syndetics:

In her debut novel of what she calls "spirited romance for the Jane Austen soul," author Linore Rose Burkard tells the intriguing story of Miss Ariana Forsythe, a young woman caught between her love for a man who doesn't share her faith and her resolution to marry only a fellow believer in Christ. Trouble at home sends the young woman to her aunt's townhome in the fashionable Mayfair district of London. There she finds worse troubles than those that prompted her flight from home. Ariana is soon neck-deep in high society and at odds with Mr. Phillip Mornay, London's current darling rogue. Then a scandal changes Ariana forever. Her heart, her faith, and her future are all at stake in an unexpected adventure that gains even the Prince Regent's attention. Will Ariana's faith survive this test? And what about her heart? For it's Ariana's heart that most threatens to betray the truths she has always believed in. When she finds herself backed against a wall, betrothed to the wrong young man, how can it ever turn out right? Jane Austen readers and fans of Regency romances everywhere will love Before the Season Ends.
