Blue Sisters by Coco Mellors

I very much enjoyed this book, which is not overly long and not overly complicated, yet is able to deliver on some well loved themes for me. The four sisters Blue grow up in a tiny New York City apartment--the six of them sharing two bedrooms. So there is all the potential sibling rivalry at hand but it is subverted by an alcoholic abusive father and a mother who protects him over her children. So they are prone to wanting and needing to escape and they are more bonded to each other than might have otherwise happened. The story revolves around the accidental overdose death of the third sister from fentanyl and the grief that engulfs them in the aftermath. There is addiction in all sorts of manifestations, there is difficultly with intimacy, and there is generational grief, which is kind of a trifecta for a mental health professional, with general appeal for all.
