Reviled by his family, hated by many, he's earned his reputation in the seedy streets of London and more than his fair share of bedchambers.

Lord Peter deVere, Earl of Dunsford, is not at all who Mariah imagined marrying, but she is willing to take a chance on the older man in order to gain the freedom that only married women are allowed.

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.
