The three Blue sisters are exceptional--and exceptionally different. Avery, the eldest and a recovering heroin addict turned strait-laced lawyer, lives with her wife in London; Bonnie, a former boxer, works as a bouncer in Los Angeles following a devastating defeat; and Lucky, the youngest, models in Paris while trying to outrun her hard-partying ways. They also had a fourth sister, Nicky, whose unexpected death left the family reeling. A year later, as they each navigate grief, addiction, and ambition, they find they must return to New York to stop the sale of the apartment they were raised in.
