From Jessica Knoll—author of Luckiest Girl Alive, the instant New York Times bestseller and the bestselling debut novel of 2015—comes a blisteringly paced thriller starring two sisters who join the cast of a reality TV series. One won’t make it out alive. So…who did it?

When five hyper-successful women agree to appear on a reality series set in New York City called Goal Diggers, the producers never expect the season will end in murder…

Brett’s the fan favorite. Tattooed and only twenty-seven, the meteoric success of her spin studio—and her recent engagement to her girlfriend—has made her the object of jealousy and vitriol from her castmates.

Kelly, Brett’s older sister and business partner, is the most recent recruit, dismissed as a hanger-on by veteran cast. The golden child growing up, she defers to Brett now—a role which requires her to protect their shocking secret.

Stephanie, the first black cast member and the oldest, is a successful bestselling author of erotic novels. There have long been whispers about her hot, non-working actor-husband and his wandering eye, but this season the focus is on the rift that has opened between her and Brett, former best friends—and resentment soon breeds contempt.

The Favorite Sister explores the invisible barriers that prevent women from rising up the ranks in today’s America—and offers a scathing take on the oft-lionized bonds of sisterhood, and the relentless pressure to stay young, relevant, and salable.
