'Once a Wallflower, At Last His Love' by Christi Caldwell is book six in the "Scandalous Season".
This is the story of Miss Hermione Rogers and Sebastian Fitzhugh, the 5th Duke of Mallen. Book 1 in this series 'Forever Betrothed, Never the Bride' does have Sebastian in it due to the first book in the series was about his sister. In addition Sebastian turns up in book 2 'Never Courted, Suddenly Wed' also. You don't have to have read the other books to enjoy this one but I just wanted to let you know so you would have all the information.
Hermione has been taking over caring for her family since her mother has died and this has left their father rather lost in his thoughts. So to earn money she has started writing a book to help also take care of her older sister who due to a illness has been left a child's mind but in a women's body.
In addition she is being made to try and make a match from a wealthy man to help support her family. Sebastian is finding Hermione to be a distraction and a mystery.
With Ms. Caldwelll writing she takes you on a emotional journey with her books and this one was no different. Loved It.
