Four very different characters, each at a crucial point in their lives, receive a mysterious invitation to a vineyard estate in the South of France to drink the oldest bottle of wine in the world. Avery must supplement the meagre income from her sommelier job with influencer deals that damage her reputation, Cosmo is the world's youngest Master Sommelier but his life is in freefall, while Sonny is the wealthy owner of a tacky mass-market wine brand and acerbic Maëlys is a restaurant critic with secret sorrows of her own. It seems at first that these four have little in common except their love of wine but perhaps the right bottle can change that. Over the course of several days, they indulge in delicious food and drink, engage in raucous debauchery, and confront hard truths that will leave them changed forever. Romantic, bittersweet and wise, Lush is as sensuous as a summer afternoon among the vines and as funny as your best friends on their worst behaviour.
