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.
