Jared Langley, present-day Duke of Reston, tumbles into an abandoned fountain on his ducal estate and travels back in time to the year 1816. There, Reston servants and local villagers think him a dead ringer for his namesake and rakehell ancestor-the seventh Duke of Reston, gone missing at the Battle of Waterloo. Unfortunately, Seven got mixed up with French spies out to assassinate the Duke of Wellington, and an unwary Jared ends up in their crosshairs. Lady Ariana Hart has loved Jared Langley, the seventh Duke of Reston, since she was twelve years old, until the night the rogue broke her heart. Given up for dead, her rakish neighbor makes a miraculous return from Waterloo-only Jared shows up a changed man and reignites all the feelings Ariana had long ago buried. Jared is in a race against time. He must waylay the suspicions of his quirky servants and neighbors, get to Wellington before the French spies do, fix his fountain-before Seven shows up-so Jared has a way home, and definitely not fall in love with the irresistible Lady Ariana.
