A Regency Valentine (Lovers and Ladies #4.5)
Kitty Grey, Carola Dunn, Ellen Fitzgerald, Jo Beverley, Sheila Simonson

Among Mrs. Trent's guests are Juno, whose strong principles and bluestocking ways seem too great a challenge for any man. But she had a romantic heart - and love finds a way.
Shy Philo, pretty and clever, but overshadowed by her charming and handsome older sister. It is Philo who first catches a gentleman's eye, when she meets the mysterious young man whom village rumour calls a wizard.
Aquila, a seemingly cold and haughty beauty, fears that scandal in her family's past will keep her from the man she loves. But that dashing gentleman has other ideas.
And pretty Katherine grew up without love and affection. Her well-meaning mistakes may cost her the man she loves.
Mrs. Trent would have her hands full sorting out lovers' tangles - if she herself were not distracted by the arrival of a man she knew long ago who has returned just in time for St. Valentine's Day.
