After her former band shot to superstardom without her, Claire reluctantly agrees to a gig as a playgroup musician for overprivileged infants on New York's Park Avenue. Claire is surprised to discover that she is smitten with her new employers, a welcoming clique of wellness addicts with impossibly shiny hair, who whirl from juice cleanse to overpriced miracle vitamins to spin class with limitless energy. There is perfect hostess Whitney who is on the brink of social-media stardom and just needs to find a way to keep her perfect life from falling apart. Caustically funny, recent stay-at-home mom Amara who is struggling to embrace her new identity. And old money, veteran mom Gwen who never misses an opportunity to dole out parenting advice. But as Claire grows closer to the cool women who pay her bills, she uncovers secrets and betrayals that no amount of activated charcoal can fix. Filled with humor and shocking twists, Happy and You Know It is a brilliant take on motherhood - exposing it as yet another way for society to pass judgment on women - while also exploring the baffling magnetism of curated social-media lives that are designed to make us feel unworthy. But, ultimately, this dazzling novel celebrates the unlikely bonds that form, and the power that can be unlocked, when a group of very different women is thrown together when each is at her most vulnerable.
