Sweetbitter by Stephanie Danler
Tess comes to Manhattan full of hope and soon finds herself working as a "backwaiter" in a famous downtown restaurant. She gets an education in fine dining, even finer wines, and she gets drawn into a seductive love triangle: drugs, friendship, loyalty, lust, and love. Sweetbitter is a lush, un-put-down-able novel that will seduce you and draw you completely into its world. Not to be missed.
