Jordan Barrister loves her grandfather, her unique candle creations, and the life she's built in present day Chicago. Her latest hobby obsessions, however, are love locks from a section of grille purchased at auction from Paris' famed Pont des Arts pedestrian bridge. She's determined to create a lasting tribute to those who put a lock on the bridge to safeguard their love. While a lock is normally used to keep something in, one particular lock accidentally opens a time portal and Jordan finds herself in 1926 Chicago.
Reporter Henry Douglas wants a more intriguing story than interviewing a magician named Harry Houdini. He is a man with a mission, on the trail of Chicago's gangsters and bootleggers, crooked police and the man who shot his brother. His life doesn't include beautiful mystery women falling into his arms out of nowhere. But there's something about Jordan that intrigues him and discovering her secrets might be an even better story. He shouldn't be surprised that along the way, he finds the other half of his heart.
In the beginning, all Jordan wants is to return to her own time, and she believes the now missing lock holds the key, but she needs Henry's help to navigate this unknown period of history. By the time they discover the lock's whereabouts and are in pursuit, she has fallen in love and wonders if she really wants to return to the present. How can she let go of the man who holds the key to her heart? When disaster strikes, they will need to use what they discovered to find the magic of the love lock that will keep their hearts together.
