Graham, Lord Blakemore, was believed to be lost at sea as a boy. While his mother, Lady Agatha, has never given up hope of finding her son again, others - eager for the title and the wealth that accompanies it - have been conspiring to have him declared dead against Lady Agatha's wishes.

His requirements are precise: she must be capable of mothering the wild twin daughters who have unexpectedly appeared in his life, and so must possess the patience of a saint and the understanding of an angel. Better still if she is plain and has no expectation of a true marriage. He is not about to reform his ways.

So desperate in fact, that she’s willing to do the unthinkable - propose marriage to the most surly, irritable gentleman in town.
