Chance of Love — Amanda Mariel

Lady Lenora St. Martin is shy and a wallflower. She has no idea how to interact in society so when Julian Everleigh, the Duke of Ashley asks her to dance at a ball she falls completely in love with him. After that one dance he doesn't seem to notice her again and Lenora has to discover a way to break out of her shell on her own and vows never to love again. As she flourishes Julian takes notice and decides she's the only lady for him, but he may have already lost his chance of having her love.
