From New York Times bestselling author Mary Balogh comes the third novel in the Horsemen Trilogy, in which a proper English lady discovers how desirable she really is after one very improper night... Sophia Armitage does not consider herself attractive. Even her late husband treated her more as a companion than a lover when she accompanied him to war. But Sophia hopes to enjoy a Season in London as her niece makes her social debut—until, that is, her hopes are dashed when she is faced with a threat she can reveal to no one. Then she meets Sir Nathaniel Gascoigne, an old army friend, and falls in love with him even as she must discourage his growing passion for her. Nathaniel can sense Sophia's unhappiness and fear, but does not understand that his attempts to protect and help her can only bring about her downfall... | Irresistible by Mary Balogh, Mass Market Paperback | Indigo Chapters
