From the author of the Good Morning America Book Club pick Count My Lies, soon to be a Hulu series starring Lindsay Lohan and Shailene Woodley, comes a sharply addictive novel about a woman desperate to infiltrate an exclusive circle of mothers-until she realizes their magnetic ringleader has a dangerous game of her own

Mallory Greene is drowning in her new normal: new house, new coast, young kids, and a husband who's become increasingly distant. Which is why the Sweet Hill moms are so important.

Mallory's heard the rumors-they're exclusive, ruthless, and powerful enough to make or break anyone in town. So when their charismatic leader, Natalie, finally takes notice of her, Mallory is thrilled. For the first time in months, she feels seen.

Mallory soon learns that the Sweet Hill moms play a private game they call "confessions" at their evening gatherings, each woman revealing a secret the others could destroy her with. It's intoxicating. And cruel. Mallory, with secrets of her own, must decide who she can trust and what she should reveal, including the real reason she wanted to join the Sweet Hill circle.

But as her friendships with the women deepen, Mallory begins to suspect she wasn't invited into the circle at random. Someone wants her right where she is, and what she thought was a game is something far more deadly. Mallory will have to choose where her loyalties lie-and what she's willing to do to prove it.
