The enemy of my enemy is my lover

The former Comtesse de Retha, Mabel Meadows, isn't thrilled about being in London. After her miserable marriage ended two years ago, she had hoped never to cross the Atlantic Ocean again. Yet with her father too busy with work back home in Philadelphia, and her sister newly engaged to an English peer, she has no choice. Acting as her sister's chaperone, Mabel intends to return home soon enough.

Derek, the Earl of Trembley, has been having a difficult time taking over the Earldom since his father's passing. In the blink of an eye, everything has changed, and it seems everyone is moving on besides him. Despite his apparent composure, he's under immense pressure and is anxious to maintain the status quo. When his brother returns from a visit to America with a fiancée, Derek feels unbalanced, and what's worse; he meets his brash but beautiful future sister-in-law.
