To Love and to Loathe by Martha Waters- Paperback

The only thing they can agree on is that the winner takes all . . .

The widowed Diana, Lady Templeton, and Jeremy, Marquess of Willingham, are as infamous for their bickering as for their flirtation.

Shortly before a fortnight-long house party at Jeremy's country estate, Diana is shocked when he appears at her home with an unexpected proposition.

After finding his latest mistress unimpressed with his bedroom skills, Jeremy suggests that they embark on a brief affair. He trusts Diana to critique him honestly, and she'll use the gossip to signal to other gentlemen that she is interested in taking a lover.

Diana has bet Jeremy that he will marry within the year, and she intends to use his proposal to her advantage.

But in this battle, should the real wager be who will lose their heart to the other first?
