It is 2013, and twenty-three-year-old Brooklyn barista Molly Diamond has just locked eyes with Jake Danner, the front man of an up-and-coming Southern rock band. It's not long before Molly and Jake fall deeply in love, planning for a life together filled with creativity, passion, and adventure.

But nearly a decade later, Molly is teaching yoga and living in a posh Connecticut suburb with her young daughter and husband, Hunter - who is decidedly not Jake Danner. Molly is lonely in picture-perfect Flynn Cove - until Sabrina walks into her studio. A newcomer in town, Sabrina has her own reasons for seeking out Molly, and their blossoming friendship will set both women on a collision course of deep-rooted secrets, lies, and manipulation.
