Sometimes, the romance of a lifetime starts with one perfect night.

It's the year 1885 and the world has just begun giving up its ancient secrets. Miss Charlotte Blakely is a librarian in Rome. She's researching evidence of the fabled Veil of Veronica, but her time abroad is drawing to a close. Her viscount father is dying and has called his children home, yet a chance encounter with a stranger one balmy night might change her direction.

Mr. Everett Desmond is the English ambassador to Rome. He's dashing and would have been daring had he gone down a different path, but being jilted at the altar sent him far from England and sordid memories. Now, life has grown staid and boring. When he literally crashes into a pretty lady on the street, he's intrigued enough to further an acquaintance.

Desire flares after a couple of moonlit strolls, and a kiss at the Trevi fountain irrevocably changes both of their lives. Budding romance blooms beneath the heat and they find themselves enchanted enough to land into potential scandal. Is it a love to last a lifetime or is it merely a moonlight indiscretion? Only they can decide what they truly want for the future.
