One invitation. A lifetime of regrets.

Sweet sixteen. It's an exciting coming-of-age, a milestone, and a rite of passage. Jeff and Kim Sanders plan on throwing a party for their daughter, Hannah--a sweet girl with good grades and nice friends. Rather than an extravagant, indulgent affair, they invite four girls over for pizza, cake, movies, and a sleepover. What could possibly go wrong?

But things do go wrong, horrifically so, and Jeff and Kim's flawless life in a wealthy San Francisco suburb suddenly begins to come apart. In the ugly aftermath, friends become enemies, dark secrets are revealed in the Sanders' marriage, and the truth about their perfect daughter is exposed.

Perfect for fans of Big Little Lies, this is a white-knuckled and "riveting tale that is impossible to put down" (Bill Clegg, New York Times bestselling author of Did You Ever Have a Family).
