What an incredible piece of reporting. Keefe has made his own contribution to the genre, staring (at real personal risk, if his epilogue is to be believed) into the abyss of the opioid epidemic to find the monsters responsible, and the reader can't look away. The pace of this book is exactly as slow as it needs to be to communicate the depth of callous cruelty exercised by the Sackler family and the extent to which they are culpable for this atrocity. For understanding the origin of the tragedy afflicting the country, you can't do better, but shit if it won't fuck your blood pressure
