The Mistress Diaries by Julianne MacLean

From bestselling author Julianne MacLean comes a grand historical romance series set in the lavish palace of an English duke, where duty and desire collide. He told me he would treat my heart with great care. He was lying of course, for it was all a very clever, skillful seduction… Cassandra Montrose cannot deny that she lost her head a year ago when she was whisked out of a London ballroom by Lord Vincent Sinclair, the most desirable man she'd ever met. She never imagined that she could engage in such wicked behavior with a man she barely knew, but in that heated moment, alone in his coach, the passion she felt for him was undeniable—even though she knew that after her surrender, she was unlikely to ever see her lover again. Until a fateful secret brings her to his door… Cassandra always believed that her pride would prevent her from becoming any man’s mistress – especially a rogue like Vincent, who cares for nothing but his inheritance. But she has a very good reason to remain in his life. If only he did not tempt her so… “Passionate romance that will keep you up all night!” – New York Times bestselling author, Elizabeth Hoyt “Enthralling, passionate, and suspenseful till the very last page is turned…” – ReaderToReader.com
