There's a word for that / Sloane Tanen.

"Introducing the Kesslers: Marty, a retired LA film producer whose self-worth has been eroded by age and a late-in-life passion for opioids; his daughter Janine, former child star suffering the aftereffects of a life in the public eye; and granddaughter Hailey, the "less-than" twin sister, whose inferiority complex takes a most unexpected turn. Nearly six thousand miles away, in London, celebrated author Bunny Small, Marty's long-forgotten first wife, has her own problems: a "preposterous" case of writer's block, a monstrous drinking habit, and a son who has fled halfway around the world to escape her. When Marty's pill-popping gets out of hand and Bunny's boozing reaches crisis proportions, a perfect storm of dysfunction brings them all together at Directions, Malibu's most exclusive and absurd rehab center. But for all their failings, the members of this estranged--and strange--family love each other."--
