Years before Audrey St. Vrain was born, her mother, Camilla, shot to fame with Letters to My Someday Daughter, a self-help book encouraging women to treat themselves with the same love and care they’d treat their own daughters. While the world considers Audrey lucky to have Camilla for a mother, the truth is that Audrey knows a different side of being the someday daughter. Shipped off to boarding school when she was eleven, she feels more like a promotional tool than a member of Camilla’s family. Audrey is determined to create her own identity aside from being Camilla’s daughter, and she’s looking forward to a prestigious summer premed program with her boyfriend before heading to college and finally breaking free from her mother’s world. But when Camilla asks Audrey to go on tour with her to promote the book’s anniversary, Audrey can’t help but think that this is the last, best chance to figure out how they fit into each other’s lives—not as the someday daughter and someday mother, but as themselves, just as they are. What Audrey doesn’t know is that spending the summer with Camilla and her tour staff—including the disarmingly honest, distressingly cute video intern, Silas—will upset everything she’s so carefully planned for her life.
