A Scoundrel's Secret. Revenge of the Wallflowers, #16

Miss Carina Leonelli had once been the pampered daughter of an Italian barone. All that came to an end when her father fell into bankruptcy, lost everything, and then suffered a violent death. With no home to return to, she became the companion of her dearest friend and found her place among the wallflowers. Mr. Felix Knight had wanted a simple life and one that did not include his grandfather. He found that when he took the position as the coachman for a marquess.
His situation further improved when his employer brought home a wife and her sweet companion. He hopes to win Carina's heart, but will he be able to keep it when she learns the truth?
