The funny, heartwarming, and completely charming first novel from Liane Moriarty, the #1 New York Times bestselling author of Nine Perfect Strangers and Big Little Lies.

Lyn, Cat, and Gemma Kettle, beautiful thirty-three-year-old triplets, seem to attract attention everywhere they go. Together, laughter, drama, and mayhem follow them, but apart, each is dealing with her own share of ups and downs.

Lyn has organized her life into one big checklist, Cat has just learned a startling secret about her marriage, and Gemma, who bolts every time a relationship hits the six-month mark, holds out hope for lasting love.

In this wise, witty, and hilarious novel, we follow the Kettle sisters through their tumultuous thirty-third year as they deal with sibling rivalry and secrets, revelations and relationships, unfaithful husbands and unthinkable decisions, and the fabulous, frustrating life of forever being part of a trio.
