The Marquess Takes a Fall — Amy Lake

Fiona Marwick, a young widow, acquires an unexpected houseguest when the Marquess of Carinbrooke takes a tumble on the cliff near her home. Their attraction grows during his lordship's enforced convalescence from a broken leg, but complications arise when the marquess' sister arrives, with news of a supposed fiancée. And in the meantime, the dastardly Sir Irwin Ampthill has other plans for Fiona -- and her land.
