The Loveless Duke by Patricia Haverton

“I can’t marry you knowing you will never love me in return”
Lady Alicia has all but cultivated her reputation as a bluestocking. A fact she regrets now, that she is in desperate need of a match. A match to save her and her family…
Richard, the Duke of Galpin, refuses to fall in love. Even as his mother nags him daily, he knows where his priorities lie. Still, when he realizes the stunning, opinionated lady he met at a ball is in need, he devises a plan to help them both.
They agree to marry on one condition: neither one is allowed to fall in love! When Alicia realizes she cannot keep that vow, she has a choice to make: marry him without saying a word, or speak and lose him forever…
