"A fascinating exploration of the dangers of social media . . . smart and timely."--Carola Lovering, author of Tell Me Lies and Bye, Baby

For fans of Ashley Winstead, Jessica Knoll, and Jo Piazza, an electric debut thriller about what happens when one of the first child stars of the social media age grows up . . . and goes missing.

Hazel Davis is drifting: she's stalled in her career, living in a city she hates, and less successful than her younger sister, @evelyn, a mega-popular lifestyle influencer. Evie came of age online, having gone viral at five years old for a heart-tugging daddy-daughter dance. Ten years older and spotlight-averse, Hazel managed to dodge the family YouTube channel--so although she can barely afford her apartment, at least she made her own way.

Evie is eighteen now, with a multimillion-dollar career and unlimited opportunities, but Hazel is still protective of her little sister and skeptical of the way everyone seems to want a piece of her: Evie's followers, her YouTuber boyfriend and influencer frenemies, and their opportunistic mother. So when Evie disappears one day--during an unsettling live stream that cuts out midsentence--Hazel is horrified to have her worst instincts proven right.

As theories about Evie's disappearance tear through the internet, inspiring hashtags, Reddit threads, podcast episodes, and scorn, Hazel throws herself into the darkest parts of her sister's world to untangle the threads of truth. After all, Hazel knows Evie better than anyone else . . . doesn't she?
