There's Always Tomorrow. Twickenham Time Travel Romance

Melanie wishes there were real gentlemen still in the world. Her dating life is a joke so when she hears about a week-long Regency immersion experience at Twickenham Manor in England she happily books a trip. After an almost perfect week, and wishing she could prolong her stay, Melanie is surprised to find herself transported back in time to Victorian England in the year 1851. Sir Jack Hughes has had enough of the flirtatious young ladies and their meddling mothers.
When he meets Melanie, another one of Aunt Nellie's visitors from the Americas, he's happy to make her acquaintance, yet cautious. He can't lose his heart again to another visiting American. As the two spend time together, they agree to pretend to go along with Aunt Nellie's matchmaking schemes in order to avoid the other eligible guests at the manor. But when they come to enjoy each other's company more than they expected, how can they ever find common ground if they aren't even from the same century?
