Lady Maggie's Challenge. The Buckingham Sisters, #1

Lady Maggie enters society for the first time, only to have a Duke with nefarious intent exert controlling behaviour under the guise of interest. A series of events related to the Duke makes Lady Maggie concerned for her reputation and future, but when Captain Devine comes to her aid, she is smitten. Wanting to avoid the Duke's interest, Lady Maggie accepts invitations to less prestigious occasions.
After the first event's success, her friends are pleased, but the disdain and rudeness levelled at  Maggie at their second event stun them all. Confused and sad, Maggie opts out of social affairs, and when her friends learn the truth about her treatment, it becomes clear that the Duke has been complicit in spreading false rumours. To save her reputation, Maggie and Theo marry, and for a time, all goes well.
The Duke's threats towards Maggie seem empty until Lady Maggie is abducted and held prisoner in an abandoned building. The Duke rations Lady Maggie's food, imagining she will eventually offer her services in exchange for food, but Maggie has no intention of succumbing to the Duke's wishes. When her husband rescues her, Lady Maggie imagines her trials are done, but when Lord Devine doubts her truthfulness, she flees to the country.
After her husband's lack of trust, will Maggie be able to forgive him, or has he ruined their relationship forever?
