Sometimes the prettiest Instagram feeds mask the darkest, and bloodiest, secrets.

Social media influencer Summer Cartwright leads a very charmed life: millions of followers, the hottest designer and vintage clothes at her fingertips, a newly minted book deal, the coolest friends, and, until recently, the hottest boyfriend at her über-elite prep school. Every moment of her life has been carefully planned and cultivated to complement her “imperfectly perfect” social media persona. She is truly #LivingHerBestLife.

But when Summer goes missing during her annual Halloween party and then an unscheduled post appears on her feed stating that she’ll be dead within the next five minutes, those closest to Summer know something isn’t quite right—or on-brand. Grace, Summer’s camera-shy best friend; Adam, Summer’s gamer ex-boyfriend; Laney, Summer’s moody camp roommate; and Cora, an influencer wannabe, all decide to investigate. And when they come upon Summer’s lifeless body, they soon realize that no filter is strong enough to mask the lies we tell ourselves.

Told in multiple POVs interspersed with social media posts and flashbacks, Live Your Best Lie has twists and turns that will keep readers turning the page and no one will be able to guess the ending.
