Art historian Camille Leray has spent her career surrounding herself with fineries and selling pieces worth millions. But she harbors a secret: she has the ability to enter the world of any piece of artwork, and she can take others with her. But tapping into history comes with great risks. And someone has been watching, someone who knows about her magic…and her mistakes. After Camille ruins her career and reputation by misusing her powers, she vows to get her old life back. So when Maxime Foucault, an enigmatic aristocrat who owns a sprawling French estate, enlists her help in authenticating the statues of a mysterious artist, she knows this could be her chance to turn her career around and get the man she's always wanted. But something isn't right about the Foucault family and the grand chateau they inhabit.

Lou feels like she is stuck on the wrong path: alone, in a city far from home, watching other people be happy. When the man she's in love with announces his engagement to someone else, Lou is consumed by “what ifs.” That's when she finds herself slipping back in time to a night two years ago, when one small decision changed everything. Suddenly, Lou has a chance to fix her mistakes. But as her choices lead her down roads she never could have imagined, she finds herself stuck in a time loop of her own making. And with each slip, Lou notices her life intersecting with one person again and again. A friend of a friend who once lived on the periphery, who is slowly becoming the one person who makes her feel like she finally might be on the right track.
