A Virgin for a Vow by Melanie Milburne

Her innocence–exposed!As London’s top relationship columnist, Abby Hart can’t tell anyone her biggest secret: not only is her perfect fiance entirely fictional, she is also utterly untouched. Invited to attend a prestigious charity ball with her “husband-to-be,” she throws herself upon the mercy of brooding millionaire Luke Shelverton.

After his own engagement ended tragically, Luke is reluctant to take credit for Abby’s diamond ring. To protect her reputation, he agrees to a convenient arrangement. Except Abby’s effervescence kindles a fire he’s tempted to indulge… And uncovering her innocence compels Luke to initiate his temporary fiancee into all the sinful delights of the bridal bed!
