Some call her a cult leader. Others, their salvation. I used to call her my best friend…Ten years ago, seventeen-year-olds Katie and Frida spent a heatwave summer together on a tidal island and they haven’t spoken since. Katie has tried hard to forget about what happened, all while watching Frida rise to fame as a spiritual influencer with millions of devoted followers. But then a photograph surfaces: a group of girls bathed in summer light, white t-shirts glowing against marsh water. One figure is the celebrated Frida Rae. One is Katie. The others are girls whose dead bodies recently washed up near the island. As a determined journalist starts asking questions, Katie’s carefully constructed life as a doctor’s wife and a mother begins to crack. Forced to recall her time with Frida, she is drawn back into a world of obsession, toxic first love and deadly secrets. Frida has many faces: victim, friend, spiritual leader. But how far will both women go to protect their image—and whose story will the world believe?
