Chloe has always dreamed of becoming a bestselling writer. Then she meets Clara Holland, a prominent influencer, socialite, and model. Clara is enigmatic, dazzling, gorgeous. And at last, ordinary Chloe has something to write about.

Bonding instantly, Chloe moves into Clara’s grand family estate. They spend long afternoons together, writing Clara’s memoir, polishing social media posts, and planning sumptuous, decadent parties: fairy lights in the orangery, themed cocktails, sequined backdrops, roaring bonfires. But as Clara opens her home to more girls who want to live like her and inspire one another, the media calls them a cult.

As life becomes more claustrophobic, Chloe begins to hear unsettling rumors about Clara. When a girl goes missing after a spectacular New Year’s Eve party, the rumors take on a sinister new meaning. If she can’t escape Clara’s influence, everything Chloe holds dear may be in danger.
