The Truth About Lord Stoneville by Sabrina Jeffries

Lord Stoneville is the eldest of 5 grown siblings, his parents died when he was young, and since then the Sharpe siblings have been looked after by their feisty brewery-managing grandmother. It comes as a shock to all the Sharpes when Gran tells all 5 they have 1 year to be married or she's cutting them all off.
Oliver, Lord Stoneville, does not want to be married and thinks he can end his grandmother's threat by bringing home a most inappropriate woman as his intended. Maria Butterfield, an American, is searching for her missing fiance, and the path leads her and her cousin Freddy to a brothel. Which is where Oliver finds her and saves the pair from being hung as thieves. Not doing it just out of the goodness of his heart, Oliver forces a promise from Maria to act as his fiance in front of his grandmother. She agrees in order to not be sent to jail and to secure Oliver's help in finding her fiance.
Being a romance novel, mishaps occur, misunderstandings take place, seduction happens, and the pair that seem mismatched ends up together. I didn't think Jeffries writes with the same sense of humor as Julia Quinn, but I enjoyed the book. The historical setting is good, the story good, the supporting characters interesting (each of the Sharpe siblings will have his or her own book, and 2 additional have been published), and ending happy. I enjoyed it, a good light read and I look forward to reading the rest.
